My body is messing with my head!

I went off the pill in April bc hubby and I are ttc no 3. Got my period (in April right after)  then we planned to wait another month before really trying. AF was due May 19th...never came! Instead got positive OPK on may 24th!?! We BD and now I have no idea when to expect my period!!! Tested yesterday (neg) and trying to wait at least till the weekend to test again. Mother Nature is messing with my head!
