FTM so I'm not positive on what contractions feel like but I was cramping yesterday after I got done swimming. So today I started having a tight cramp pain go from my lower back into my stomach and I started timing them . They were 5,6 minutes apart and lasted 25-30 seconds for a good hour. then they started coming every 10 minutes but were getting more intense. Then they kinda stopped and are coming every 15 minutes, and Now theyre back to every 5 minutes. Any ideas on what I should do??
