I love my doppler I rented one from bellybeats probably the same kind you have. It worked at 10 weeks for me, but it was a little hard to find the hb some days so don't get discouraged.
ive lost the same about 6-7 lbs and im eating and drinking allllll the time!
Yea I'm trying to get plenty of fluids. It's actual fat/tissue weight. I've dropped weight around my upper middle area. It's noticeable.
I drink as much of fluids as I can a day.
Weight loss can be quite normal during early pregnancy especially if you have bad nausea/vomiting.
Make sure you are getting plenty of fluids. Sudden weight loss (5 or so Ibs/week) is most likely water loss and you dont want to get too dehydrated. You need a minimum of about 64 oz/day.
