Tummy tightenings

Rainbow

Hi all.

Currently 23 weeks pregnant and for the past couple of weeks I've been having lower tummy tightenings...

Not painful but I feel it get really tight and uncomfortable and lasts between 10-20 seconds then relaxes again.

Today I've had around 6 tightenings.

Has anybody had this? There not painful so haven't felt the need to call the midwife, and have read about braxton hicks, but thought maybe it's too soon for that !.
