Sleeping on a balloon

I hate getting up at night to go to the bathroom. I don't really want to be wandering the house when it's dark and I should be sleeping. I put it off as frequently as possible. Lately that means that first thing in the morning I have to run to the bathroom and miss the morning cuddle time with Husband. As soon as I get up, he does. :(

This morning as I tried to convince my body it could hold out longer, it felt as though I had a small balloon in my lower abdomen. Different from full bladder feeling, though that was there, it was like sleeping on a small ball. Side note: I prefer to sleep on my stomach and am very unhappy that I'll have to give that up soon. I'm getting all the stomach sleeping I can right now.

I think it's the first time I've actually felt pregnant. My OB told me my uterus is twice the size it normally is. I doubt I'm really supposed to be feeling much differet, but it felt like something was there and it wasn't normal.
