My baby is gonna be 2 months on May 21st and I just got my period yesterday so maybe give it some time . :)
But if you are having unprotected sex just maybe check to make sure just to be safe if it doesn’t come around. Your body is still healing and now that you started your period early you can be ovulating again which is likely you can get pregnant very easy.
Id say it’s normal to have an irregular period after having a baby as ur hormones are trying to regulate. I just had my first period at 9 weeks pp and I’m also on birth control. It lasted 10 days which is not normal for me before I had my baby.
