How common is it to get a false negative pregnancy test 4 days after missed period?

I am 27 years old with a 3 year old son. My husband and I have been trying to conceive our second child since July of 2008 with one blighted ovuum pregnancy in December 2008. We did not find out about the blighted ovuum until we went in for our 10 week visit where the doctor found the embryonic sac, but no baby. Now, 9 months later I am 4 days late. This is not normal for me because my monthly cycle is like clockwork. My cycles are exactly 30 days and I know that I ovulated on day 16 of my cycle because I used an ovulation predictor test. Here I am 4 days late using a Clear Blue digital pregnancy test that was negative. I'm curious because I think that implantation may have happened on the day of my expected period. I had quite a bit of mild cramping and I found a slightly brownish/redish tinged mucus when I wiped after using the restroom. This only happened that one time. I'm wondering if it's possible that it's still too early if implantation didn't happen until 14 days after ovulation. My face has broken out, i've been having mild cramping off and on with no bleeding, mild nosebleeds, my breasts are larger and extremely tender and painful, and I've had horrible ongoing heartburn. I'm pretty positive that I'm pregnant, but since I keep getting negatives I'm concerned that maybe it's another blighted ovuum pregnancy. I would appreciate any advice or experiences anyone has had where they had false negatives so late in their cycle.

Thanks for the advice. I actually started my period this morning so I'm kind of bummed about that since it's now been 17 months of trying. Oh well, I guess there's next month.

I'm so sorry. I have been where you are, and I know just how you feel. It's very difficult.

My advice? Take December off from trying. I know you can't put it out of your mind entirely, but it's a month filled with holiday errands and extra pressures and budget craziness, and that stress doesn't help at all when you're trying to conceive. Taking some of the stress off of yourself may help you a bit. And while I know that each month brings new hope and new chances to try, I also know the downside of the rollercoaster. Maybe you can give yourself a break from it during the holidays?

Best of luck to you. May your New Year bring that hoped-for babe.

I can understand your frustration, concern and confusion!

For most women, a home pregnancy test is 99% effective at detecting the "pregnancy hormones" once a missed period has occurred.

There is a chance that it was too early, even if just by a day. If you can, try to wait another 3-5 days and take another test. (I know---easier said than done!). Any symptoms you are feeling now may/may not be early pregnancy symptoms. Most women do not have heartburn-related pregnancy until they are further along. Breast tenderness can be hormone-related, either due to pregnancy or upcoming period.

I hope this information helps, but you may also want to call your doctor's office to ask their advice, since you have had a history of a blighted ovum pregnancy (although you would most likely have a positive pregnancy test if you had another blighted ovum).

How do you feel about waiting another 3-5 days...is this doable?
