Dilation question!!

I've seen some posts where it seems like some ladies doctors told them their dilation & effacement could mean they won't make it to due date..
I'm 34+5 and a few days ago I was dilated 1cm, 50% effaced & my OB was pretty surprised & sent me to L&D for monitoring because of Braxton hicks also. 
Anyone have any input on this lol? I wasn't concerned before and that's why I didn't ask questions, now I feel like I definitely should have  😳
