i found this on a website... because i am only 8-9 dpo and keep getting negatives... i was thinking..wow shouldn't i be able to get one now since im due for my period on the 27... well that is i am on a 26 day cycle...uhh well here's some info for those of you who havent seen this website before

 

What Are My Chances Being Pregnant With a Negative Pregnancy Test? Am I Pregnant?

A repeatedly negative pregnancy test when you missed your period means that you are not pregnant and after a week of a missed period with negative pregnancy tests your chance being pregnant is 1%.
Pregnancy TestThe timing of a positive pregnancy test depends on implantation. If you are pregnant then a urine pregnancy test is not expected to be positive until at the very earliest 3-4 days after implantation, which is about 10 dpo days after ovulation/fertilization (4 days before the next period), and about 51% of pregnant women have a positive pregnancy test 2 days before the expected next period. What are your chances of still being pregnant when you are trying to conceive and have a negative pregnancy test? What are your chances getting a positive HPT if you are pregnant? Below is a table showing your chances of still being pregnant with a negative pregnancy test on different days of your menstrual cycle:

Pregnancy Chances after a Negative Pregnancy Test in Relationship to Ovulation and the Days before or after the Expected Period
Days Post
Ovulation
(DPO)
Day of
Expected
Period (EP)
Chance of Still Being Pregnant with a Negative HPT     Chance of NOT Being Pregnant with a Negative HPT %  of Pregnant Women with a positive Pregnancy Test
12 DPO EP -3 12.3% 87.8% 51%
13 DPO EP -2 9.5% 90.5% 62%
14 DPO EP -1 8.0% 92.0% 68%
15 DPO Expected period 6.5% 93.5% 74%
16 DPO EP +1 5.3% 94.8% 79%
17 DPO EP +2 3.8% 96.3% 85%
18 DPO EP +3 2.5% 97.5% 90%
23 DPO EP +7 1% 99.0% 96%

Date are based on the fact that in each menstrual cycle there is an about 25% chance of getting pregnant as well as a scientific study published by Wilcox in JAMA in 2001.
Your chance of getting pregnant each month may be different depending on your age, certain medical issues, whether you ovulate or not, and if your are trying to get pregnant with IVF or other fertility medications.

Besides being pregnant, the next reason for missing your period is not ovulating (anovulation). That's why it's essential for every woman who TTC to chart her fertility and to know precisely each cycle if ovulation happened or not. Knowing if and when you ovulated usually removes any confusion you may have if your period didn't come. Start charting your fertility NOW. It helps you find out if you ovulated, whether you are fertile, and it will let you know early on if you are pregnant. If you know you ovulated and your period hasn't come 15+ DPO, then there could be only one reason: You are pregnant. If you know that you did not ovulate then you can often expect your period not to come and you are prepared for that.

I find that really interesting... My last AF was Nov 19th. I know that I O'd on Dec 1st or 2nd at the latest as I had all the signs and temp changes and all.

Af was due Dec 17th. Neg HPT. Decided not to test anymore and just wait... Went to ER on Dec 22nd with bad cramping and migraine.. Neg Urine test.. Dec 26th, My neice told me at Christmas dinner that I was having a baby and it was going to be a girl... So I woke up on the 26th and decided to test since I still had no AF.. To my surprise I got my BFP. Faint but it was there.

I am in the group that HCG doesnt metabolise in my urine until several weeks later. This is actually kind of common and seems to be this way for everyone in my family. My mother didnt get a positive pregnancy test (HPT) with me until she was already 5 months along!

Just have some hope hun. It will happen!

Finally Pregnant with my First!

try again after your missed period.. we were ttc and my lmp was dec. 8 i was supposed to be ovulating around the 22 i tested around new years and it was negative i tested a week after and it was still negative.. i went ahead and waited until i was a week past my missed period and i had faint positives on all tests... so i made an appt with the doctor and they did a blood test and an u/s and i am pregnant... according to my lmp im 6 weeks and 3 days, but due to my u/s the docotr thinks i may be less weeks... i go back in 2 weeks to do another u/s.... don't give up and retest on the day of your missed period... good luck!
