Hi... I need some help diagnosing my lower stomach. I don't know if this is relevant but I last had sex in March this year and it was unprotected. I've had five periods since then and waiting on my sixth. I've noticed my lower stomach bloat out from under my belly button at different times since March. As I breath in and out the lower stomach still seems to be slightly sticking out? I don't know if I'm just bloated there or if pregnancy is possible but I worry about things like this all the time so I just need some reassurance please! Please respond ASAP! Thank you.
