I will be 25 weeks tomorrow and have been feeling pretty good. We went to the zoo today and after a couple of hours I started to get some pretty bad cramping on my right side, the it moved to my left side and was pretty consistent on both sides until we got into the car. It was actually pretty painful, enough for my SO to know I was uncomfortable. I was drinking water consistently throughout the day and had no bleeding or anything. Is this normal or has it happened to anyone else after being active for a few hours? Baby is fine. She's movin around in there and has been pretty active all day/night. I did not call the dr because it subsided and like I said there wasn't any bleeding.
