Me and my gf had unprotected sex on aug 27, she had her period on sep 6, she's currently experiencing a bloated tummy (bad food & electric fan focused on her at all times). is she pregnant? need dire help, she said her period was normal?

First of all, you need to have a rule for yourself that you never have unprotected sex. Likewise for your girlfriend if she is sexually active, best to use regular birth control. Best for your girlfriend to take a pregnancy test if she or you are concerned about pregnancy. A bloated tummy can have several causes and and best your girlfriend be seen at a clinic/doctor to determine the cause.
