I had it twice. I am sorry to say on the first time it caused the placenta to break away from the uterus and I had a late term miscarriage. On the second one I had to basically go to the Dr. every 3 days and have my blood pressure checked. The same thing happened with the placenta tearing but I was rushed to the hospital and they said basically , He's hanging on. I then had to have lots of time on my back to keep the blood pressure stable. I am mentioning the placenta tearing because it is very scary.....lots and lots of blood involved in this, but like I said, it doesnt mean it wont turn out ok. I ended up having my son 1 month early, and he was perfectly healthy. Take care of yourself and dont feel guilty about putting your feet up and resting all that you possibly can.
