We found out over 3 weeks ago we were expecting. I am 7 weeks. When I first weighed myself (4wks), compared to my weight tonight (7wks), I've lost roughly 12 lbs. I am a bigger girl and my weight became high when I stopped eating during the day except for a late lunch and dinner. Now that I've found out I'm pregnant, I eat a lot of small meals through out the day. I assume I boosted my metabolism. Has anyone else had this happened????
