So I'm flying on Tuesday and I'll be 27 weeks, when I fly home I'll be 30 weeks. I had no idea until today that I needed a fit to fly letter after 28 weeks. I thought it was only if you were 34 weeks plus. I've seen that private online gps will do one for £50 and I was wondering if anyone else has done this? This is my third pregnancy and I'm low risk. All my babies have been born at full term. I have no idea what to do as I've heard gps won't sign one. Any advice would be appreciated.
