unwanted weight loss

I called my dr & we're waiting for a call back so I figured I'd ask on here while I'm waiting. I weighed 121.4 yesterday, then got on the exact same scale today & it said 118.4. I haven't ate any less, peed anymore, etc so I'm confused as to how I could lose 3 lbs in 1 day.Also, you know how some days you have more of a bump than others, well yesterday I looked huge & today you can't tell that I'm 26 weeks pregnant. But I have felt her move today so as far as I know she's still doing alright in there.

Hi Breanne,
I just found your post. I had the same problem when I was pregnant. One morning I woke up and noticed that my tummy is smaller. I didn't think of it anything that time but I should have. I lots my baby at 27 weeks. He didn't have enough amniotic fluid. Anyway, can you let me know what your doctor said?
Thanks
Mari
