Maybe thats what it is. I don't want to call the doctor with every little question and it doesn't hurt so i was going to ask at my next appt. But i posted to see if anyone here knew.
When I was around 9 to 14 weeks or so when I had a full bladder it pushed the baby up and my tummy would be hard. After I peed it would go back to being soft. Maybe that is what's going on with you.
k..... does it disapear at any point in the day? Like after you wake up and move around or go pee?
I know for me, I get a bit tighter when I wake up, and right before bed. But during the day my stomach is just soft.
not to sound gross or anything, but have you had a bowel movement? If not, then that could be what your are feeling.
