I'm 39. I tracked ovulation this month and I got a peak on day 17, all other days were low LH. We had sex on day 18. My cycle is anywhere between 26-30 days. Today is CD 31, still no period. I've had 2 negative pregnancy tests with a cheap brand off Amazon (same batch) which I've since checked reviews for and there's a few cases of false negatives (and false positives), so they don't seem to be the most reliable brand. If my ovulation day was correct (day 17 peak) then I'm 14dpo today and I tested negative with those cheap tests on 12 & 13 dpo.
Can anyone shed any light on what's going on here? Could I still be pregnant? Thank you
