Just needed to ask a question and get some advice from others.

I've been seeing 2 different doctor's, one is my regular obgyn and the other is a high risk doctor. I just saw my high risk today and he said there might be antibodies in my blood. (I am rh o negative) also they think my preeclampsia will be setting soon. (im only 26 weeks) I'm starting to get nervous because they keep bringing up having an emergency csection sooner than later to get him out. I've had 2 emergency csections before but not till 37-38 weeks due to preeclampsia. My question is has anyone dealt with anything like this? And has anyone given birth to a micro preemie and suceeded? I'm nervous he won't make it or something will go wrong :( I also don't know the process after he's born or how long it'll be before I get to take him home? Any advice also on what to pack for a possible hospital bag? I want to be as ready as possible.
