Mmm.. i had that yesterday. AF (may be) due in next few days...? Interesting. Although after 13 years of being on the pill, it's also entirely possible that these are AF symptoms I just didn't experience before! .
I have a seriously erratic cycle (at best) so it's all very hit and miss.
In my experience (4 pregnancies) implanatation feels like zingy little pains that start around pubic area and move down my inside legs. I had these every time. Ovulation pains are dull and stay in one place for me. Good luck OhBling.
Well, I'm increasingly certain it is AF as I'm starting to feel more "normal" AF twinges that I used to get even on the pill.
This is not in fact a bad thing as it would mean I have at least a vaguelly regular cycle which puts me far ahead of where I thought I'd be at this stage. It's nice to be in the position that AF is almost as good as a BFP.
