So I am 8 weeks pp, had my first pp period last month. (About 2 weeks ago maybe, if that.)

I’ve been feeling good, I’m on the mini pill (have been since 3 weeks pp) , take it same time everyday. I have resumed sexual activities.

Tonight I have been having severe like cramping and ache just on my left side in my abdomen... is that normal?? What could cause this? Any help works! Thanks!
