Okay, so I have a 23 day cycle. I have ALWAYS been on time for AF. However, we have been BD for the past few months and using OPKs (we actually ran out before I got high or peak indication this month, so I just had to go off of the days this app predicted, and what I thought I felt) as well trying to conceive baby #2. I was suppose to get AF two days ago, and absolutely no sign whatsoever. My cervix was low, but yesterday it went up so far I can't reach it. I've taken pregnancy tests yesterday and this morning and they're both negative. Could I have ovulated later than I think and I just dont have enough HCG yet to give a positive? Maybe my period is just all of the sudden off? I've never been late for AF, so it's just weird! Also, I have had a HUGE increase in CM since Monday. It's off white/clear and lots of it. Just wondering if anyone might have an idea or has experienced this? Thanks ladies!!!
