34 weeks pregnant and 1 cm dilated, anyone been there?

How long did your pregnancy last after you found this out? I obviously really want to make it to 37 weeks at least. My Dr. was so nonchalant delivering the dilated news and said she thinks I have a couple weeks left and we’ll do a growth ultrasound at 36 weeks. I’m having contractions but I guess they’re mild? This is my first pregnancy. They feel like Charlie horses and come and go all day & night. I’m definitely not ready, I know everyone says you never really are, but please keep the comments positive because I’m super nervous. Thank you for reading this!!
