Pms early ? Please help

Audrey
Is it normal to feel like your PMSing extremely bad like a week and a half to two weeks before your next period ? Me and my boyfriend had unprotected sex a little before I started feeling like this and he came inside of me. We never use protection and usually use the pull out method.. but not this time. And like the last couple days I've felt SO emotional, extremely insecure, bloating, nausea , bad pelvic pain and little things like that. does anybody know if this is just normal?
