Moving abroad while pregnant ????

Me and my fiancé are struggling financially in our home country, I’m just about to be 8 months pregnant and we are struggling keep up with our needs & bills, food, medicine for me and overall our financial situation here is harder and less help is offered here for families, so we spoke to my parents who live abroad in the uk where I was raised. I moved out last year to live in my home country with my fiancé. So we are thinking of moving out to my parents who offered to help at start with the baby so we can get back on our feet so we have an easier time raising our little man who is due in September. However I’m struggling to decide if we should move before I give birth and have everything there in the uk when baby comes or wait till I give birth here and then move with the baby. What would you ladies do ? Wait for baby to come? Or do everything before ? And if we do decide to move before birth then we are thinking to move just before I hit 35 weeks will flying be safe or will it be a bit too risky ??
