Bed rest started today. Its not helping. Idk what to do. Help please! Scared.

Went to see my OB today to recheck my cervical length. Not only is it now funneling, but it dropped from a 3.2 to a 2.6 in the last week and a half. He's referred me to a perinatologist whom I see next Thursday, put me on bed rest and emphasized the motrin therapy. 600 mg every 6 hrs.

He, (we) cant figure out why im contracting the way I am. He said a length of 2.5 is his "limit" and being at 2.6 doesn't really make much difference to him.

My concern is, even though im in bed, and taking the motrin, im still contracting. Though not near as much, but still have random bad contractions, the lower back pain and massive pelvic pressure. I dont see anyone again until next Thursday and at this point, im worried my water may break or something may happen by then. Im only 25 weeks.

I dont know what to do. Should I call my doctor again tomorrow? He said if I get bad enough, I'll probably be admitted. But after hearing him say baby's only have a 50/50 shot at this gestational age. .. who cares. He needs to keep cooking. :( help. Advise please?
