Do I have a bladder infection or am I pregnant?

The first day of my last period was on July 21st and my period is regular, which lasts 6 days.. I had unprotected sex all of those days and then frequently after.. The past 4 days I had unprotected sex 6 times.. I've been having funny feelings in my stomach right where my belly button is and sometimes like right above my hip bones, one night I woke up at 3 in the morning with a pain in my side that made me curl up in a ball. and I've been having like hot flashes and I've been extremly moody.. Im very bloated and it constantly feels like I have something in my stomach... the "pain" in my stomach is not nessecarily a pain but it's just an annoying feeling.. also I've been having to pee a lot, and I think I have a bladder infection.. could all of these symptoms result from the bladder infection or is it more likely for me to be pregnant?

It could be either or my best bet for you is to take a pregnency test...n if that ends up bein negative I would go see your doctor.
