Possible pregnancy |HELP!|

14|| So I've had sex many times with my "bf" and we use protection usually but sometimes we don't. He usually cums on my stomach and lately I've been more exhausted then normal, I have been having weird stomach pains, I've been Urinating a lot also which is weird for me. // If I am pregnant I'd be I think about 5/6ish weeks? I'm not quite sure but if someone could tell me their early symptoms? I'm not showing or anything I'm just bloated.
