I'm 23 weeks with a due date of 9/11. The past two days, I've had 10-15 contractions and although I wouldn't put them past a 7 on the pain scale (usually 5 or 6), they're making me nervous. Soonest I can see my doctor is next Monday. Should I go to the ER? I was there 10 days ago having 3 contractions in an hour and they told me not to worry about it and drink tons of water and take iron supplements. I've been doing that, but the contractions are only seeming to come more frequently. What should I do?
