So I had a baby in January 2018 and went on the depo shot in March. I bled for 7 weeks straight. The other shot was due on May 28 but when I went to the clinic they were out of stock. I decided to take the pill because I don't want anymore babies and my fiance' was coming from overseas in June. This would have been my first sex encounter since giving birth so I know it was going to be epic. I started taking the pill on June 1. My period came on the 29th of June and lasted for 8 days. I'm off the pill since then because I'm not sexually active(my fiance' is not here now) but my period has not returned. What could be possibly wrong with me?
