I need an extra tank...

Okay, so I already have a small bladder. Beginning at week 6 I was already getting up twice per night to use the bathroom. As my uterus grows, I have to go even more and I'm only at 4 months! I think I'm going to need to carry a catheter and bag around as I get closer to 9 months. I realize that this is God's way of preparing us for the lack of sleep when the baby comes, but can't I ENJOY my sleep now knowing that I won't have any for a few months when the baby comes? Geez. I need an overflow tank for my bladder so I don't have to go so much.
