Well I've got 2 kids and one on the way this pg I suffered with HG for nearly 4mnths couldn't get out of bed low blood pressure all the joys...NOT! It was the most horrible experience.

But with my 1st pg I had what I would call average M/S for a couple of months but could still function, and with my 2nd pg none at all!

So like Kristie said everyones different as with all pregnancies, but I completely understand why you're scared!
