I am 16 weeks pregnant and so far i have lost 3 pounds in 5 days. i know my weight is supposed to fluctuate but is that normal?this makes 7 in a month

Worrisome : This is worrisome since you should be gaining weight at this stage of pregnancy. Talk to your obstetrician so testing can be done to find and correct the problem. Best wishes for you and the baby.

Depends: If you are losing weight and are nauseated and vomiting, you may be dehydrated and need IV fluids. Some women just don't feel like eating in the first half of pregnancy and lose weight even though they are not vomiting. This isn't known to harm baby. Most women will gain weight after 20 weeks. A good target is a pound a week. Best wishes!
