What type of weight gain is normal when you're 19 weeks pregnant?

A weight gain of between five to ten pounds is normal between the 17th and 20th weeks of pregnancy, according to WebMD. The ideal amount of weight gain is dependent upon the woman's pre-pregnancy weight, her body mass index, and the health of the pregnant woman and the fetus.

The normal amount of overall weight gain during pregnancy for a woman of normal weight is between 25 to 35 pounds, according to the Mayo Clinic. The appropriate amount of weight gain is lower for overweight and obese women. For women carrying multiples, the normal amount of weight gain is higher, between 37 and 54 pounds.
