What do contractions feel like???

T

Hey ladies!

This morning at 6:45 AM I lost my mucus plug. I’m currently 38 weeks 6 days. Ever since I have been having these random cramping and tightening feelings that last 20 seconds and they’re starting to get more consistent. They don’t hurt too bad and they aren’t getting more intense. Does that mean they are Braxton Hicks??? Or contractions??? Or neither??? FTM here so I have no idea what’s going on. Any help or advise is very much appreciated!!!
