are you getting contractions on and off??

Just curious to know what everybody else is going through. I'm 37 weeks and two days, for the past couple of days I've been having lots of cramping that feels like period Pains. On Sunday I had contractions for about an hour which were mild and regular but then they stopped. Then last night at 2 AM for two hours they came every 2 to 3 minutes were painful but then stopped again. For the past three days I've started my walking and committed to walking at least a mile a day. It does feel painful at times when I walk like pressure and sharp pain in the cervix. If your babies are due in May what are you guys feeling now?? No leakage of fluid or bloody show or mucous plug for me yet. I was on progesterone daily for preterm labor and had stopped for about a week and a half now.
