I had my first child by cesarean section 8 years ago and got my period back 1 month after giving birth. Now, it's been more than 3 months since I had my second child by cesarean section and I still haven't had my period back. Both children are exclusively breastfed. Do I have any problems? How long does it take for the first-period return after a cesarean section?

Hello doctor! My period is 28 days, on February 25th I had my period and on March 20th I had sex. Doctor, can I get pregnant? I hope you can advise me. Thank you!
