35 weeks

Well I'm 35 weeks now and I had my OB and NST today which they also checked my cervix. So now i have been losing my mucus plug since this afternoon since the cervix check. I have to ask because I'm still on the high risk list of any moms have experienced the same and carried full term still or if i should make preparations for a likely early birth? When she checked the cervix she didnt have to go all the way in to feel the babys head and then she went further to check and be sure.

Of course I'll be talking with my doctor but i just want a few moms opinions. This is my 4th baby but I've never had problems like I've had with this one
