Has anyone ever had bad experiences with this birth control pill? I was on it years ago for my endometriosis and never had a problem .. now a few months after baby I've been really sick! (Nausea, cramps, back ache, headaches, spotting, tummy troubles)  I really don't want to be on birth control but figured it'd contain my endo and we also can't afford to be pregnant again( although I wouldn't mind😕)At first I thought I coulda been pregnant but all the tests say negative. Seems to be getting worse every day. Any thoughts? Which birth control do you prefer?
