For past several weeks my lower abdomen in my pelvic region has been sticking out hard and bloated right between my hips. I noticed it after having sex 2 weeks ago and now it will not go away. I don't not think I am pregnant and would not show this soon i think. I had my period end a little more than 2 weeks ago and should be getting it next week. There is very mild cramping in the area but I mostly notice that it is Sticking out what would this be?
