Hi doctor.. I am 30 years old, 7 weeks with my first pregnancy and no history of miscarriage. I have to fly on Feb 15th for 4 hours. Went to doctor to check if it's safe to fly at 9 weeks. She asked to go ahead but prescribed me progesterone shots and duphaston 10 mg. She didn't check for my progesterone levels at all. She prescribed to avoid miscarriage while travelling. I took one shot and the tablets for 2 days but now confused whether to continue or not. Please help.
