So AF was due today, if I had luckily gone straight back to a 28 day cycle. Yesterday there was a slight pinkish colour when I wiped once, nothing since. Last night I got dizzy, sweaty and had horrendous cramps and was on the loo for half hour, unable to move! Then was fine again. No AF so far today. I still have a twingey cramp on the left since suspected ovulation. I did a negative test Monday, if no show tomorrow would you do another? Obviously I don't know when AF will show as first cycle after pill.
