Possibly changing delivery date lol

Today was my 34 week check up (I’m 33 wk 6 days). I measured at 36cm in the fundus which puts me two weeks ahead of schedule. The baby on the last ultrasound has measured ahead too. For the last 48 hours I’ve been dealing with cramping and more annoying Braxton Hicks. Plus the sharp vaginal pains that are associated with “lightening crotch”. Although my cervix is closed as of today, my doctor is concerned that I could possibly dilate between now and next week’s appointment. I am drinking tons of water and trying to relax as much as possible. I am tracking the cramps and the BH. And tracking the movement of the baby too. I am supposed to have a scheduled c-section at 39 weeks but I am not so sure that I will be making it to that point.
