Birth control

Sydney
I've been on the pill for about two months now and my boyfriend and I have sex almost everyday. he pulls out every time. I'm not sure if it's from the pill and all the hormones, but my breasts are so swollen and in pain (like I've never experienced this pain before) and I'm bloating to the max, and having really bad cravings. like I can't stop eating. is this birth control hormones or should I be worried?
