Girls, can you please tell me who flew on vacation at the 8th-11th week of pregnancy? If there is no threat, can you fly or not? On the appointment date is 7th, and tickets are on the 8th, I read online that it doesn't harm if there is no threat, but you can lose the baby and stay home lying down for 9 months. Tell me your experience.
