Stopped Birth control😩

So I stopped my birth control about a month ago and I've been having the weirdest side effects 😩!!! My nipples are soooo sore and my upper rib area feels kind of like a light burning sensation on the skin. I've also been having light cramps in the back of my thighs. I'm terrified bc I just lost my mother to stage four breast cancer a month ago. I'm scheduling me a doctors appointment sometime this week. Has anyone else experienced anything like this ? (I also took two pregnancy tests and they were both negative)
