with the GD, you are definitely able to ask for extra monitoring in the latter stages of PG rather than opting for an induction. fwiw, with my DS i was offered induction at 38 weeks but said i would prefer until i hit the 40 weeks. i ended up being induced right on 40 weeks & while the outcome wasn't too bad (had an assisted vaginal delivery - with forceps), it still wasn't what i had hoped & it would have been a c-section if the forceps hadn't worked.

this time round i found they were far more relaxed with both me & my GD - levels still controlled (with insulin) but they seemed to trust that i wasn't such a high risk because i'd had a vaginal birth previously that was considered fairly stock standard. this time i had my DD on my due date but i avoided the hospital induction it would seem by getting gastro which put me into labour (i was booked in for an induction the following week but managed to escape it!)

are you insulin-dep for the GD? that's when they are a little more wary but it depends on how many units of insulin a day you're on. i would suggest that you speak to the ob & ask under what circumstances he would want to induce at 38 weeks. bearing in mind too that scans at this stage in PG are notoriously unreliable. if your BSLs are good, you're not on a big dose of insulin & you can have monitoring, then i'd be inclined to say you'd rather wait. especially if you've had stress-free previous PG/births.

you can use raspberry leaf tea, evening primrose oil, clary sage etc but i'm inclined to think these things only work if your body is getting ready anyway.

fwiw, i don't recommend gastro to help induce you especially not when the whole family gets it & no one has any sleep for 48 hours before trying to push out a baby

not too long to go now - good luck (and feel free to PM me if you want to chat more about the GD stuff)
