When you’re experiencing a singleton pregnancy you very well know what to expect and what’s the average size your belly will take. But with a twin pregnancy, you are thrown into the unknown regarding your twin pregnancy belly. Is it big enough for two, or is it too big for two? The questions start arising and the belly starts sizing. 

There is no right or wrong answer, and whatever symptoms you are experiencing you should know that they are completely normal. That’s the beauty of twin pregnancy – it comes as a surprise and acts like one.

We are here to help you be in the know about what each week of your twin pregnancy will bring you, and most importantly, how to be comfortable with your twin pregnancy belly.

5 Weeks Pregnant with Twins

While it might seem that you are still very early in your twin pregnancy, you shouldn’t exclude the possibility of experiencing pregnancy symptoms. This can range from the well-known morning sickness and breast tenderness to drowsiness and frequent urination.

In order to ease the symptoms when 5 weeks pregnant with twins we recommend you to start eating healthy and avoid strenuous exercises in order to prevent a miscarriage or a vanishing twin syndrome
