LADIES!! I need your thoughts and opinions‼️

Ok so I think I’m going crazy but I have been feeling so weird lately. My boyfriend and I never use protection. I’m not on any kind of birth control. And we have sex normally. My last period was so much shorter and lighter than its ever been. I’ve been having these weird cramps in my lower abdomen and I have like a weird flutter feeling below my belly button. I’ve been getting crazy headaches and heart burn. I have also been sporadically hungry. And when I get that way my hunger never seems to be met. My period isn’t supposed to start for another 11 days, so I know I can’t test and expect an answer. Could you guys give me some ideas or your thoughts on the situation? Have you ever felt this way and what were your out comes?
