I had a baby 5 months ago. Two months ago I started to become extremely bloaded, I have to pee about every 30 minutes, I have lower back pain and my stomach feels really firm and it sometimes hurts. I just had my period. I am a tummy sleeper and can no longer sleep on my tummy becuase there is just too much pressure and then I have to go pee even more because something gets pushed down on my bladder. The doctor gave me Vesicare and it isnt working I still have to go to the bathroom more than ever. What is wrong with my stomach??
