Pink discharge?

Jade

Hi so I basically ended my period on the 18th (which was about 7 days ago) and for two days (TMI) I’ve been having a little bit of light pink discharge when I wipe ? Ive been sexually active w my husband using protection but recently we didn’t have any half way through my period ? Idk what to think of this bc ive never had seen that type of discharge before ? I’m also 2m pp and I know it’s easy to get pregnant after you have a baby ? Idk is this just my body cleaning itself out or ...? I also been having headaches and weird dry mouth and today the right side of my pelvic hurts and achy ness in my back?lol ( idk if that has anything to do with it ) or could that mean ovulation?
