abdominal SWELLING....not normally a sign of pregnancy....or not that i think? bloating, yes sometimes....SWELLING can be a mile-long list of things, some more life-threatening than pregnancy.....if you get a negative test, you need to see a dr....you could be having anything from an ectopic pregnancy, to real stomach issues, and your organs are not something you want to play games with.....
If your wondering if you are pregnant there is absolutely no way a group of stranger on the internet can tell you. Take a pregnancy test. If money is an issue they sell very reliable ones at the dollar store.
hmmmm.......can I guess? I say sure, why not?
