Preeclampsia and 2nd pregnancy

Amnesty • Mommy to Aurora born at 31w2d, Declan born at 37w0d and Connor and Liam due 1/31/2018.
My daughter was born at 31+2 weeks via c-section due to me developing severe preeclampsia. After a 6 week nicu stay we got to bring her home and she is now about to turn 2. This morning I got a little faint line on a test and have been a ball of mixed emotions since. Has anyone here had a normal pregnancy after having preeclampsia? My husband is joining the military and will most likely miss the birth of this child if the dates his recruiter estimated are correct for when he will go to boot camp and ait. So if things go downhill I will most likely end up with a nicu stay when the closest nicu is an hour and a half away with a 2 year old still at home. It may be a stretch but I'm kind of looking to ease my mind a bit.
