Okay, so I need some help. My last period was August 20th. I should have ovulated on 9/9 and started my next period on 9/22 (13 DPO). But I completely missed that period. I took pregnancy tests on 9/26 (17 DPO), 9/28 (19 DPO), and 10/2 (23 DPO). At that point I figured I had just missed it because of stress or something (even though I've NEVER missed a period before), so I started taking ovulation tests the next week. I got positive LH tests from 10/8-10/12, at which point I decided to take a pregnancy test because i heard that LH tests pick up positive pregnancy results as well. Well, I note have positive pregnancy tests from 10/12-10/15. So... I'm pretty sure I'm pregnant, but it seems like it's way too early for me to have ovulated again. Is it possible that I just got negative tests to 23 DPO even though i was pregnant?
