I have been having really sharp pains in my rectum and lower abdomen. When I try to have a bowl movement the pain worsens as well as when I try to pass gas. I have noticed that it seems to happen when I am getting ready to start my period and during my period, and my uterus seems swollen as well. Can someone please tell me what they think this could be?

Obviously I need to go to the Doc but until I can make it to the Doc I just wanted to see if there is others having the same symptoms as me.
