I had my son on August 31st, and got my first period on November 29th But never got it again in December. Is it possible Its still irregular? Im not breastfeeeding but I am trying to relactate and pump on occasion (although I don't get hardly anything out) I'm not too worried but my SO is starting to worry he even came to me and said December 12th we had sex, unprotected but he didn't orgasm, I know there's still a chance but I'm hoping my periods just irregular from having a baby.
