I had my son September 22nd. I had my first period November 13-16th. I was supposed to start my period on the 8th of December again according to glow but it’s still not here. I’m getting really nervous because my husband “accidentally” came in me about a week & half ago. I’m not breastfeeding. I’m just curious if it’s just thrown off since I gave birth almost 3 months ago?
