Help, I can’t enter a new weight!

You can only log weights in the App that fall within your actual weeks of pregnancy. The first day you can log a weight is the first day of your pregnancy. The last day you can log your pregnancy weight is day 294 of your pregnancy (last day of 'current' week 42).

How much weight should I gain?

The amount of weight that you should gain during your pregnancy depends partly on the weight that you started out with. Whether you are having one baby or two, or multiple babies, will also play a factor in determining your optimum weight gain over the nine months of your pregnancy. This will be something you will discuss with your doctor early on in your pregnancy.

An underweight woman will need to gain more weight to support her pregnancy and her baby’s needs, while an overweight woman will likely not need to gain quite as much. A woman who starts her pregnancy at a normal weight for her height and build will still need to gain an ideal amount of weight.

A woman who is underweight at the beginning of her pregnancy will need to gain, on average, between 28 and 40 pounds (13 and 18 kilos) during her pregnancy. A woman who starts her pregnancy at a normal weight will need to gain between 25 and 35 pounds (11 and 16 kilos), while an overweight woman will only need to gain between 15 and 25 pounds (7 and 11 kilos). A woman who is expecting twins can gain between 35 and 45 pounds (16 and 20 kilos). All these values are based on your starting weight and should be discussed with your doctor.

The usual weight gain is about 2 to 4 pounds (1-2 kilos) each month in your first trimester and about 1 pound each week after that. A twin pregnancy will result in an average gain of 1.5 pounds each week after the first trimester.

It may seem like a lot of extra weight, but when you see the way it is broken down, you’ll realise that much of this weight is for temporary and necessary pregnancy requirements and not just fat, which makes up only a fraction of your total gain. Keep in mind that these are averages, and your baby may weigh more or less than this.

Your baby will weigh between 7 and 8 pounds at birth. Both the placenta and amniotic fluid will weigh between 2 and 3 pounds each. The increase in your breast tissue will account for another 2 to 3 pounds and the extra blood in your circulatory system will weigh about 4 pounds. This leaves only 5 to 9 pounds for fat stores and 2 to 5 pounds for your uterus.

If you’re having twins the weight of your babies will be slightly more, about 12 to 14 pounds and there will be a slight increase in the weight of other components as well.
