Ok I've been having intense "period-like" cramps for the past hour and 45 minutes. They haven't gotten worse but they haven't gotten better. Some waves are worse than others tho. I can feel it throughout my entire stomach from top to bottom. No gas or anything. I drunk 2 cups of water and lied down but it's still there... I can walk around fine but I feel it and it's not pleasant... Should I just go to the hospital? These don't feel normal.
