incompetent cervix baby #2

I am 23, 5'0, 240lb.

I am (about) 6 weeks pregnant with baby #2.

first OB appoiment 01/30/18. (about 8 weeks along then)

I delivered. @ 29 weeks with my first, completely silent labor. went in at 3cm 80% effaced. transferred to another higher level hospital with an amazing NICU. The high risk doctor said he suspected IC after we delivered.

give me advice? what did your docs do to help you stay pregnant? in freaking out.
