Hello im 18 years old and i have had a distended stomach for the past three monthes. I can suck it in and its not hard but when i relax it bloats out and looks like im 6 monthes pregnant. I have not had sex for the past three monthes and i have gotten my period normally for all three monthes. I also took two home pregnancy tests with negative results. I sometimes get a bubbly feeling in my stmach which feels like sotmhing is moving in there. Thsi is making me so paranoid that i may be pregnant. But i really dont think it is possible. Im on birth control and use a condom everytime. If anyone can explain this PLEASE help me calm my nerves.
