I'm pregnant with my second baby. With my first I gained weight at a normal rate. By 18 weeks I had gained 12lb. This time I lost weight from a tummy bug and sickness so Dr gave me meds, now I'm fine but still losing weight just more slowly. Now 9lb lighter. Is that normal?

It can be normal. Your doctor or midwife, if concerned, can do a scan to determine what baby's growth has been like. If they don't seem concerned about it, try not to as well... (not always easy to do!). Some women will lose a fair amount of weight in the first trimester especially, due to morning sickness and fluctuations in appetite.

It can take a little time to get your appetite back when you have been ill, and start to see the weight go the other direction. Continue to make healthy food/drink choices, and take your prenatal vitamins for extra insurance.
