Hi there - I'm hoping to gather some experiences/wisdom! 
I'm on pregnancy number 6, this is my history:
1- full term baby (emergency section delivery)
2- early miscarriage
3- twins born at 22w (no explanation, cervix just opened and went into early labour), too young to survive
4- early miscarriage
5- early miscarriage
6- now 9 weeks pregnant (single pregnancy)
Due to losing pregnancy 3 I'm wondering if I should have a cervical stitch to prevent another early birth, but have been told that as I had no problems like that with pregnancy 1 it's not necessarily needed.
Any advice? I'm almost at the end of my fertile years so this is likely to be my last pregnancy...
