well I have been having this problem for the past 3 months. The symptoms are lower abdominal pain and when I slightly pressure it when lying down it hurts and I get pain and I can hear a pulse. My stomach seems blotted with gas. I also have frequent urination problems..at first I thought I was pregnant but I've had my period the last 2 months. I took a pregnancy test twice back to back and it came out negative.. But for some reason I still have doughts. Im not sure what I have plz help!!
