Idk what's going on...

So I've started recently working out (I haven't worked out in like a year or something) and today my breasts hurt, I'm really bloated, and I have a headache... I am on the pill.. I'm curious if a mix of working out and birth control making these symptoms.. but also.. I have been having sex a lot lately.. without protection... I'm not really sure what's going on with my body. Can someone help please 😬?
