I've been having low abdominal cramps they were very light at beginning but now they seem get a little more heavy and my legs began to hurt too, and I actually feel like if i need to go to the restroom to do number 2 but in reality its just the pain and I'm kind of worry because I'm barely 22 weeks and 6days. I have no bleeding what so ever but the pain doesn't let me sleep its getting painful and annoying. Can someone please tell me if this is normal?
