Anyone else on them? I'm almost 23 weeks and my doctor has just put me on them because he believes I'm at risk for preterm labor because my cervix has been shortening and I have some fluid in my cervix although it is still closed. This is my first baby so he said he wants to try to prevent that. Anyone else going through something similar? I've really been trying not to think about it too much so I don't get worked up but it's hard now that I am seeing the doctor every week. 😕
