20 weeks pregnant

This week you’ve reached half of your pregnancy, since it’s estimated that deliveries take place around the week 40. Although, every pregnancy and every woman are different. You will have put on 5 kilos and from now on you’ll gain half a kilo every week.

The uterus has grown and it’s located where the navel is. It’s not uncommon that your heartbeats are higher since the heart has to pump more blood so that it reaches the foetus and the placenta. This provokes also that the breaths are deeper. The increase in weight and the blood flow make you feel your legs heavy, inducing the apparition of varicose veins. It’s advisable that you rest your legs regularly, apart from using loose comfortable clothes and proper shoes. If you want to wear high-heels, these must not be higher than 4 cm.

You should include in your diet food with high quantities of iron, such us red meat, legumes, fish, and spinach, and if the doctor recommends it, a multivitamin.
