Your doctor says your cervixs is 2 centimeters open and 1 centimeter shortened you are almost 36 weeks does that mean ill deliver really soon?
No - not at all. You will begin to dilate around 36 weeks and you can go 6 weeks without dilating any further. Most women are 1-2 cm dilated for the last weeks of their pregnancy. I really don't know why the doctors tell you this - it just means you worry. If you get to 4cm dilated it probably means you will go into labour soon.
You are only 29 weeks your doctor just told you i am half a centimeter dilated and 75 percent effaced what does this mean?
Your cervix must dilate (open up) to 10 centimeters before you can essentially, 'push' the baby out. So half a cm is good progress, though it seems a bit early at 29 weeks? 75% effaced: you have to be 100% effaced (thinned out) for the cervix to fully dilate & ready to deliver the baby. So you're just about finished there.
