I know it's not uncommon to develop pre e at the very end of a pregnancy so definitely keep an eye on that and watch out for any swelling in your face and hands (another red flag).
As far as the movements go - it's normal for them to slow down alot in the last couple of weeks because they just don't have the room any more. I remember I only felt stretching/squirming type movements at the end of my last pregnancy. But if you're still really worried listen to your gut and go to the hospital. They can pop you on a monitor and make sure baby isn't stressing, but her heartrate sounds fine.
