I recently had a d &c June 23. I bled up until 4 days before I got my period back July 26. I had sex during my ovulation window every other day. My next period was due AUG 26. I had light spotting that morning then nothing, next day light spotting that morning then nothing, 3rd &4th day heavy, next day nothing. So I had sex, next day light spotting. I have yet to take a test. Been moody, nausea, fatigue. What's going on?
