What do i do 40+3 and petrified-----Repost!!?

Hey everyone i know this is my 3rd so i shouldnt be so scared should i? my 1st was induced 14 days late my 2nd came on his own 2 days late but i had shoulder dystocia he was 9lb 7oz This baby was 8lb 1oz 3 weeks ago at 37 + 4 i have measured well over they even stoppped measuring me i measured 41 weeks at 36 weeks. I am so scared that the longer this baby stays in the bigger it is getting and then the same thing will happen again. Am i overreacting??????? i have a checkup with the midwife tommorrow..i know how long inductions are and i really done want to go through that again but i am so scared i dont know what to do. I have been in pain for weeks now painfull contractions that just stop after hours of having them regularly i also have spd so i havnt slept properly for weeks on end. I am finding myself in tears most days from the tiredness and pain ( and my pain threshold is quite high) Is this happenieng to anyone else or am i going mad xxxx
