Yes, you can. But first of all, it is important to listen to your body and the recommendations of your supervising physician.
In the period up to 12 weeks of pregnancy, the risk of miscarriage is high, and the pressure drop during takeoff and landing can only provoke it.
The period from 14 to 27 weeks of pregnancy is considered the safest and most comfortable time for flying.
When checking in for a flight, it is important to have a medical certificate and an exchange card with you, since airline employees may ask you to provide them.
A certificate with a medical opinion on the absence of contraindications to air travel, as well as on the absence of risk of premature birth can be obtained from the supervising physician and it is important to do this no earlier than 24 hours before the departure time indicated on the ticket.
Responsibility for your health and the health of your baby during and after the flight lies entirely with the passenger, regardless of the pregnancy period. Do not expose yourself and your baby to unnecessary risk.
