When to trust a Negative Pregnancy Test is not a False Negative

mrsnitti17 :  If you’re tracking your ovulation, then by roughly 12dpo the pregnancy tests should be fairly accurate. There are studies that show that a later implantation (past 12dpo) has a higher chance in resulting in a chemical pregnancy and not working out.

If your period is late and you are getting negatives, my guess would be that you actually ovulated later than you think you did!

mrsnitti17 :  when I was TTC the first time I’d have normal periods and then a few times a year just skip one and have a 60 day cycle. After the first week of negative tests I’d just do one every 8-9 days thereafter to be sure, but it’s likely just your cycle being wonky.

 I wouldn’t consider them false negatives. 

Sometimes it can take longer for the embryo to implant, or you just ovulated later so it just takes longer to get a positive test.

mrsnitti17 :  unless you confirmed ovulation, unfortunately there’s no surefire cutoff point; especially with PCOS. If your period is late and you’re getting negatives, it’s safe to assume you ovulated late or didn’t ovulate at all. I’d keep testing every 3 days to a week until AF shows or you get a positive — and with cheapies. 

In general though, if you’re 2 weeks past ovulation, you should get a positive test if its a viable pregnancy. It’s rare for people with confirmed ovulation dates to get later positives. Late positives usually mean late ovulation.

mrsnitti17 :  your friend did not have a false negative.  She ovulated later in her cycle and so it also took longer to implant and then get a positive test.  There really aren’t false negatives, just people who don’t know when they ovulate.  If your period is late and no BFP then you have ovulated later than normal (or potentially have not ovulated yet or anovulatory cycle).  If it is 14-15 DPO you would have a BFP, if no BFP and no period then ovulation date is incorrect.  If you’re not temping and charting you really don’t/can’t know when you have ovulated.

are you BBTing?

I did a test at 5 weeks past AF with my first and it was negative, I didnt test again until 7.5 weeks and got a strong + but I have A-typical PCOS and my main symptom is irregularity, I can have cycles ranging anywhere from 17 days to 60 days and ovulation comes when ever it feels like it. basically with so many eggs fighting for maturity the lead one can fail and ovulation doesnt occur then the next biggest tries and so on so on a bad cycle it could happen whenever or not at all.

do you take clomid?

I have used clomid and it really helps regulate my cycles, even just one or two rounds can regulate me for a year or so, for me it makes it so I ovulate regularly on day 18 and have a 9 day LP but it has yet to help me get pregnant (just regulates).

Accupuncture also regulated me too, I started after a 60 day cycle and I dont know how but it did the same as clomid and regulated me on the months I did it but still no pregnancy with that either.

mrsnitti17 :  if you do decide you want to try charting again, I would super recommend tempdrop, it’s a wearable thermometer so a lot easier to use for many people (including myself lol!) than the oral ones!
