Peeing all the time again ;(

I'm 19w2d and for the past week I've been peeing like 2 or 3 times an hour. Is the baby sitting on my blatter again? I was so happy when baby lifted off my blatter and I could go through the night without waking up to go pee! Now it's back and it sucks! Lol. Little Braxton also LOVES to kick my blatter like crazy. I was just wondering if he's sitting on my blatter & if it'll be like this the rest of my pregnancy now that it's back?
