With this pregnancy, I'm 20 weeks and think I may have felt a couple of them already, but they have only been about once a week, very infrequent, a very short, painless tightening of the uterus
and then it's gone. Tanker Chic is right

your left side
should make the go away, anything more than 4 in an hour, you should call your doctor right away.
