Me and DH have been ttc DC2 since June 2016. I came off the pill in Feb 2016 and AF was all over the place for the first few months. Then from June I had 2 29 day cycles, then the next 2 were 35 days, then a 36 day one, and my last one was 29 days again.
I tend to get a bit of cramping the 5 days before, and a little bit during AF. Bleeding is quite heavy for day 1, then gets lighter day 2, then spotting for a few days.
I'm pretty sure that I'm ovulating, I've been using opks, get lots of EWCM and get mild ovulation pain around the time that I should do. I know that it can take a while to conceive, but I'm now stressing that maybe AF is irregular and there could be something wrong?
