I've had what im guessing are Braxton hicks the past couple days. I usually don't feel them much. I just feel a tightening and my belly will get hard for about 30 seconds to a minute maybe. I'll be 26 weeks this week. I'm just not sure if it's normal to have as many as 15-20 throughout the day... anyone else experience this? like I said, they aren't painful and at most i might have one or two in a day that feel like an extremely mild menstrual cramp.
