BH and cervix question

Kaye • OB/L&D TECH. Second girl due in November. Hoping for a vbac

I have my appointment today with a new midwife (she's actually my co worker so not very nee to me but yah). In my first pregnancy I had a shortened cervix and started to dilate at 28 weeks. Is this something that should be a concern. I have so many BH contractions it's insane.
