Yeah I have had the off and on slight movement here and there, but I have done a pg test with it coming out negative. So I was just thinking it was gas. I have been bloating off and on, and have to drink a coke to belch....or take these acidophiles pills to straighten out my digestive track. I know what you mean about the stress. I am an online college student as well as wife and mom.
I wouldn't count my chickens before they're hatched. My sister went to the hospital thinking she had a kidney stone in 1985. The doc said "honey you don't have a kidney stone, you're having a baby!!". A 6 lb. 4 oz. "kidney stone". She didn't have a clue she was pregnant. She continued to have periods right along and the "slight moving feelings" as she called them, she thought was just gas. She had no prenatal care at all. Not to say you're definitely pregnant, but I would check into a home pregnancy test just to rule that out.
Personally, my OBGYN told me when I had my hysterectomy that he had a patient that had a 22 lb. fybroid tumor! He said it was as big as a pumpkin! Not sure how your periods are but if you're not bleeding heavy at all, its a possibility that your blood is feeding a "pumpkin tumor". Just a few thoughts of personal experiences in my own life. Good luck with the swollen belly. I know why mine is swollen. Comfort food and too much stresssssssssssssssss!!!!!!!!!!!!!!!!
