Do people make many jokes about weight gain during pregnancy? It is very unlikely that people would make jokes about you while you are gaining weigh during your pregnancy. Especially your family and friends will not make jokes because they know that you are pregnant. People who know about your pregnancy will also know that weight gain comes with pregnancy naturally. There is no way to not gain a certain amount of weight when you are growing another human in your body. Even if you are already overweight and do not plan to gain any additional weight, weight gain will happen. You might not be too happy about it, but it will happen. Some people, who do not know about your pregnancy, might make jokes, but they will be sorry about the jokes when they find out that you are pregnant and not fat. However, also be able to laugh at yourself.
