So I am TTC my 3rd kiddo, so I have used OPKs before, but this time I am really befuddled. Usually, I'll get almost positives for a few days leading up to ovulation before I get a clear one and then it will fade out slowly (this is when I have TTC in the past). This is my first month trying, and historically I have 30-32 day cycles and ovulate around day 17-18. I used OPKs (I know to really know for sure I should temp but I just didn't want to get that scientific about it this time quite yet) but I never got a clear positive; I got clearly negatives until the morning of cycle day 18 where I got an almost positive but the line was just barely lighter than the control line, and then later that night it was even lighter. I kept testing but never got a positive. So I am wondering if I possibly just didn't ovulate or if I maybe just missed my surge (I was working all day so I couldn't test during the afternoon when I know it is most likely to be positive). Prior to that I had worked a few night shifts so I wonder if that just threw me off? I don't know if I just missed my surge or if I never ovulated? I am now cycle day 21 and I haven't tested today yet, but I'm guessing it'll be negative.
