Losing weight.. Anyone else?

Ashley
Ok so before I got my positive hpt I weighed 119. Since I've found out about my pregnancy I've made sure I haven't skipped meals or anything I even feel like I eat more than I should. I even notice I'm showing a little.   Well I went to confirm pregnancy and had lost 4 pounds in only a week. Then I go in today for a checkup and have lost another 4 pounds! That's 8 pounds in 2 weeks and I don't see how. I know I shouldn't complain but this is completely opposite from my other  pregnancies. Anyone else experiencing this?
