My last period was 13/14 May (overnight so hard to say which day). I used an OPK Tuesday, Wednesday and Thursday this week, all negative, but was just too busy to test Friday and Yesterday. I had what I think was ovulation pain Thursday and Friday but then had EWCM yesterday (Saturday) which makes me think I ovulated yesterday. This is a test from today (11.45am), am thinking this is just slightly off positive so likely I did ovulate yesterday? 2nd month trying so still quite new to the whole process!
