Frequent urination..normal?

I'm 10 weeks and I have been going to the bathroom through the night 5-6 times, although I'm actually peeing a good amount every time. I dont drink anything past 7pm, I'm drinking water in the evenings and occasionally something with caffeine at lunch. I have some lower back pain but I am heavier, and headaches, sometimes light cramping in the evenings which I excused for the gas and bloating which also accompanies my evenings. Im just up in the bathroom so much in the night. Is this normal so early? Anyone else feeling like this?
