I've had some pretty out there dreams, don't know if it is the progesterone or if its just strange pregnancy dreams. They have definitely been vivid though.
As far as what I have been doing, I've honestly just been taking it easy whenever I can and trying to drink plenty of water. I still take my DD to almost all of her weekly activities which is 1-2 different things a day. I cook meals but try to limit the time I'm up and active when cooking or cleaning to less than 30 minutes. Mostly I'm just resting on the couch whenever I get a chance. My husband has been doing the grocery shopping and I only go out to the store 1-2 times a week for no more than 20-30 minutes and just to grab a few things not a full on grocery trip.
If I were you I would definitely push for a piece of mind scan, I don't think that hurts anything and they should do that for anyone in this situation. There are things they can do so it is really frustrating that they tell you otherwise. A scan takes a few minutes and if it helps give you a piece of mind then I think they should do it.
