Weight gain during pregnancy is a normal and necessary part of the process. The amount of weight you should gain depends on various factors such as your pre-pregnancy weight, body type, and overall health. On average, women are advised to gain between 11-16 kilograms throughout their pregnancy. However, it's important to remember that every pregnancy is different and individualized recommendations from your healthcare provider should be followed. Experiencing vomiting in the early stages of pregnancy can affect weight gain, but it's best to consult with your doctor or midwife for personalized advice based on your specific circumstances. They will monitor your overall health and ensure that both you and your baby are progressing well.
