My husband and I had unprotected sex 8 days before my period came on, and my period only lasted for 2-3 days (which is not normal for me). I did not start my birth control until right after I got off of my period. My daughter is now 4 months old. I have yet to start my period again, and I am 4 days late. I don't know if this irregularity is coming from me breastfeeding or can I possibly be pregnant again? Please help! I don't think I can handle another little one right now with my baby being this young. We haven't even had the time to fully enjoy her yet.
