Hoping someone can set me straight. I've had threaten preterm labour for the past six weeks with three trips to the hospital for medication to stop labour.

I had an u/s last week to check bubs measurement and all was well above average. On a closer look at the pic of my cervix today I noticed that my cervical length is 2.6cm whereas it had been 4.7cm at the 20wk scan.

Should my cervix be shortening naturally at this stage of pregnancy or does it have more to do with the daily constant contractions I've been having ??

Thing is I specificall asked my OB 'how is the cervix, long / closed ?" and she replied, "yep very good, long and closed".............I'm confused.

Thanks in advance
