dunno what's going on

soo last night I was doing the deed with my partner and I noticed it really started to hurt were my cervix is 🤔 like it kinda felt good but was so sensitive. now tonight just my left boob hurts, I'm talking any pressure to even my nipple 😂 my last period finished probably 3 weeks ago and I stopped taking my pill then? OH and can't forget the emotional break down I had last night, I sat there balling my eyes out because my boyfriend got salty at me and idk but I just cried for like an hour while he just held me the little darl 😅 was anyone like this early pregnancy? or is my hormones going outta whack?
