I had a postive ovulation test on the 25th November so should have ovulated either the 26th or 27the which would make me 7-8 post ovulation. I'm getting on and off cramps that feel like period cramps, I keep feeling like my period is starting then check and nothing, have had back ache right down in my lower back as well. 

Has anyone had this? 

I've been having these on/off cramps and back ache for the last few days and Google says your period should come around 12-14 days after ovulation so that's still another 4-7 days away.

Maybe I'm just over thinking.
