I'm breastfeeding my 3.5 months old baby. I used to bleed now and then for a month in first month after delivery. Later I didn't experience any kind of bleeding or spotting. However, on June 9th I had unprotected sex and took unwanted 62 within 72 hours. I experienced bleeding on 7th day of taking the pill and bleeding lasted for 3-4 days. Afterwich I have not got my periods. It's been 2 months now. Are there any chance of me being pregnant still?
