I'm 21 weeks with twins. I had a doctor appointment this morning to look at my cervix. They took me back to ultrasound and the tech looked at my cervix and was really concerned but wouldn't tell me anything. Then when I finally went back to my doctor he said my cervix is open about a finger tip. On the screen when I was being checked I could see one of the babies head right on my cervix.. He took me to a monitor room to see if I'm having contractions and it didn't show I was. But he said he suspects that I'm having really small ones that aren't showing up. I'm so scared I'm about to have a break down. And I can't even go to my boyfriend for comfort because he is 24 hours away training for a job and won't be back until Saturday. I'm going back in the morning to see if anything has changed and I'm trying not to stress about it because it'll make it worse. What can I do?! Would anything I have done caused this? Please please give me advice I can't loose these babies.
