I will be 27 weeks on Thursday, but for about 2 hours I've been having period like cramps that feel like small contractions..I drank tons of water, took hot shower,and been laying down but it's not helping... I'm waiting on a nurse from my ob office to call me back... anyone else experience this??

UPDATE:Told me to take tylenol and if they get worse or bleeding or anything like that to go to er.. if it's still the same in am then call them and they'll get me in...
