IVF concerns

So my hubby and I have decided to go for IVF treatment and have miraculously found a way to fund it. But we possibly have a career opportunity for my hubby that's out of state. Should we start it  ere or move and travel after? I don't know how fragile the process is seeing as it would be my first pregnancy--long story--but I don't know if flying means I could miscarry or just start it now and hope for the best? Anyone out there have some words of wisdom?😩
