On cycle 3, AF due on Tuesday - since coming off the pill in Nov have had 2 cycles, one of 28 days and one 29. Every month around day 14-16ish I've had a heavy feeling in my abdomen, like there's a weight there (not at all like AF cramps). I assumed that was ovulation. Used OPKs 2nd cycle and got strongest result day 19 - it wasn't a clear positive but next day had gone very faint again, after having built up over a few days. Temps for last month showed rise on day 21. I seem to have little CM (not enough to tell what sort it is!) although think I might have had EWCM on day 23 this month. Haven't been able to do either temps or OPKs properly this month due to forgetting / being away or ill etc.
Now I'm really confused about when I actually ovulate - I'd assumed that the heavy feeling, which is very noticeable, was it, but it doesn't seem to match with anything else. I'm fed up with not knowing when the right time is, and I don't want to get into the 'must SWI every other night for whole month' as that puts us both under pressure and I don't want it to become a chore.
Does anyone have any advice? I feel stupid that I can't interpret all of this!
