12 days post ovulation negative pregnancy test

I just got an early negative pregnancy test (BFN), can I still be pregnant?

The purpose of this study is to look at the statistics of early negative pregnancy tests (Commonly called BFN - Big Fat Negative in the community) when later followed by a positive pregnancy test (BFP - Big fat Positive in the community lingo) in the same cycle.

Particularly we are interested in looking at the statistics related to the timing of early negative results and the timing of a later positive result in the same cycle.

When seeing an early negative test result, most people wonder if they could still be pregnant and if they might test positive later on in the cycle. If a negative test was taken too early, the answer is most definitely, yes (Check the Chart Gallery for numerous examples). They could still be pregnant and just testing too early to see a positive result. It's interesting to look at some statistical data about these pregnancy test results.

To explore the issue of the reliability of early pregnancy tests, we looked at just under 6000 charts for which a negative pregnancy test was followed by a positive test and did not result in a miscarriage.

First Negative Pregnancy Test Before Positive

Average: 9.08 DPO (Days Past Ovulation)
Median: 9 DPO

This histogram represents the frequency distribution of first BFN when followed by a BFP. The cumulative histogram is displayed below:

By 11 DPO more than 80% of the negative have been accounted for.

First Positive Pregnancy Test After Negative

Average: 12.72 DPO
Median: 12 DPO

This histogram represents the frequency distribution of a first BFP (positive pregnancy test) when preceded by a BFN. The cumulative histogram is displayed below:

Discussion & Conclusions:

Not surprisingly, we have to wait for 14 DPO to see 80% of the positive tests accounted for. This is quite in line with a separate study that we conducted earlier although in this sample we have slightly earlier testing and most likely with more sensitive tests as well.

More interesting is the conclusion that we can draw from the BFN data. According to the community data, if you get a negative test beyond 11 DPO your chance of getting a BFP later on is significantly reduced. In other words, if you get a negative (BFN) before 11 DPO (Days Past Ovulation) there is still a good chance that you could get a positive later on.

It is also a reminder that if you can do so, you need to delay your testing as long as possible. Obviously though there are real reasons to have to test earlier beyond simple curiosity.

12 dpo, you are on the home run and likely to be just a few sweet days away from finding out if you have your bun in the oven, chances are that you may be experiencing some pregnancy symptoms now, if you are not experiencing any yet please do not worry, you may just be super lucky.

At 12 dpo (12 days post ovulation) this is still very early when it comes to there being enough pregnancy hormones (human chorionic gonadotropin otherwise known as HCG) to detect a pregnancy.

What is Happening at 12DPO (12 Days Post Ovulation)?

At 12 dpo you could be experiencing lots of pregnancy symptoms or perhaps your egg has just implanted and you haven’t yet got any pregnancy symptoms, please don’t worry. The egg can implant on any day from day 5 dpo – day 12 dpo and no person is the same.

Pregnancy or PMS at 12DPO?

This is where things get a little tricky, for many of you, your period will just be a few days away and early pregnancy symptoms are very similar to early pregnancy symptoms. When trying to conceive (ttc) it can be easy to carried away with every feeling and worried about every pms symptom as you pray for signs that you are pregnancy.

The truth is the symptoms are fairly similar, here are some symptoms at 12 DPO that can be early pregnancy symptoms but can also be pms symptoms;

• Nausea at 12 DPO
• Cramps like period cramps (cramping 12 DPO)
  
• Tender breasts at 12 DPO
• Fatigue at 12 DPO
  
• Low mood at 12 DPO
  
• Headache at 12 DPO
• Increased body temperature at 12 DPO
  

12 DPO Cramping – Period or Pregnancy

If you are experiencing cramping at 12 DPO and you are trying to conceive- it can be disheartening.

However, cramping at 12 DPO can actually be a positive sign that implantation has occured- where the fertilised egg implants itself into the lining of the uterus.

It is through this connection that the fertilised egg receives all of the nutrients and blood supply it needs to grow.

Symptoms of implantation at 12 DPO may include:

• Implantation bleeding at 12 DPO (12 DPO spotting or light bleeding that is brown or pinkish brown in colour)
• Implantation cramps at 12 DPO
• Implantation dip

Would I Get a Positive Pregnancy Test at 12 DPO?

Chances are you would get a bfn (big fat negative) at 12 dpo as it could still be too early to test on a pregnancy test.

It really depends on when you ovulated and when the egg implanted, the longer ago the egg implanted the more likely you are to have a positive home pregnancy test if you are pregnant.

Implantation at 12 DPO is possible- as implantation typically happens between 6 DPO and 12 DPO- so you could receive a positive pregnancy test. At 12 DPO, it is likely to be a faint positive.

We wouldn’t recommend that you take a pregnancy test at this stage, as a 12 DPO negative pregnancy test at this stage doesn’t confirm that you are definitely not pregnant.

If you do decide that you would like to take an early pregnancy test (12 DPO test), Clear Blue Ultra Early pregnancy tests are brilliant at detecting early pregnancies (from 6 days). You can get some here.

If you receive a negative pregnancy test result at 12 DPO, you should test again in a few days time (at least 14 DPO), as that is when the pregnancy test is likely to be much more accurate (as at 12 DPO, your hCG levels are not very high, meaning the 12 DPO pregnancy test accuracy is not great).

You can book an ultrasound pregnancy scan as early as 5 weeks pregnant.

What are Early Pregnancy Symptoms at 12 DPO?

Here is a list of some of the most popular and earliest pregnancy symptoms (12 DPO symptoms) ending in a BFP our audience of mums reported;

• Cold/flu like feeling
• Sensitive smell
• Sensitive breasts
• Implantation bleeding
• Cramps
• Fatigue
• Constipation
• Increased urination
• Dizziness

It is important to remember that it is completely normal to have no symptoms at 12 DPO.

Many women do not know they are pregnant until they miss their period (at around 4 weeks pregnant!)

Does Implantation Bleeding Always Happen After Ovulation?

Only 10% of pregnancies report implantation bleeding so if you haven’t experienced implantation bleeding this does not mean you are not pregnant and this should not be used as an accuracy when trying to predict a pregnancy. It can be difficult to know when implantation has taken place as it is different for everyone. Implantation is when the egg burys in to the womb, it does take a few days for the egg to travel to the womb and implantation can occur anywhere between 5 dpo and 12 dpo.

Is it too Early to take Folic Acid at 12 DPO?

It is never too early to start taking prenatal vitamins, we recommend taking prenatal vitamins when before trying to conceive. Folic acid is a very important prenatal vitamin. You can read more about vitamins that we recommend you take here.

What Symptoms did other MyBump2Baby Mums have at 12DPO when they had their BFP (positive pregnancy test)?

“my husband and i met late in life and i was worried about getting pregnant, we had been trying for a couple of years and then we just decided that it was time for us to stop, i keep a journal and wrote down my symptoms as i decided i wanted to start recording my cycles and moods for my own personal development and i never imagined i was pregnant, here is what i made notes of

6 dpo fatigue and sore breasts

7 dpo dizzy and feeling a little low in my mood

8 dpo i felt a strong pain in my left ovary

9 dpo cramping all day, i thought my period was on her way

10 dpo constipation and cramping

11 dpo cramps and sharp pains near my hip bone

dpo 12 body temperature was still high but i felt un well so put it down to this

12 dpo sore boobs, heavy feeling and light a lightening bold randomly soaring through them.

12 dpo pms symptoms

13 dpo cramps and headace, sensitive to smells

14 dpo postive test, i did one because i had one left over and just felt different and it was finally my bfp that we had been waiting so long for.

Fingers crossed for any of you reading this today, keep an eye on your dpo symptoms and then next month do the same and you will see if you have any different symptoms during your cycle which could indicate pregnancy.

” I should have shares in home pregnancy tests, i probably did around 14 home pregnancy tests a month when we were trying to conceive and it was so disheartening when aunt flo arrived each time. The month i got my bfp i had told myself that i am not doing it anymore, i am not filling myself with hope only to get another negative test. I stopped body scanning, stopped reading content and reviews about all of the magical things you can buy on the internet that can help you get a positive test and i decided that it was time to trust my body and just let it happen if it was going to happen. Don’t get me wrong, it took me a long time to get here, i grieved and grieved about not having any children and then finally i accepted it and jsyt thought “fingers crossed” if it happens it happens and the same month i got my positive test. I am not sure what happened but i didn’t even think i was pregnant. Infact i had no idea but when i look back i had sore boobs, low mood, nausea and cramps so the signs where there but i had just stopped looking out for them. Baby dust to you all and i hope you get your positive”
