Pain ! 😳

I've been having pain in my uterus. Mostly on the left bottom . And I've been having minor cramps I'm not even on my period. I had sex about a week and a half ago . And I lost my virginity about a month ago . . Btw i started birth control but I only lasted for a week Because I absolutely hated the side effects . I know your not supposed to or you are supposed to finish your pack but I couldn't take it anymore . Any ideas?
