Congratulations! Traveling after your third month is generally safe provided your pregnancy is uncomplicated.
Before you fly, it is crucial to get a dating ultrasound to confirm a healthy intrauterine pregnancy and rule out any bleeding risks or complications.
For the long flight to the UK, make sure to stay hydrated, walk the aisles regularly to prevent blood clots, and carry prescribed
SOS medications for nausea or emergencies.
Please consult your treating gynecologist for a final 'fit to fly' certificate before your departure.
