33 weeks hospital visit

I went to the hospital at 33 weeks exactly due to back pain that wouldn’t stop and chest pain.

I ended up being dehydrated and need medicine for the acid. They checked my dilation due to also having contractions. I was 2cm dilated but my cervix was thick. I’m 33 weeks and 3 days and have lost my mucus plug and continue to have tons of cm every time I wipe. My ob is worried due to baby is measuring 37 weeks. I do have gd and they are now monitoring me every week. I’m so worried we will have him before 36 weeks. Any one else in the same boat and still working.
