Hi Angel,

My experience with this is that it depends on your normal BP and if you have any other symptoms. Also what your Ob is comfortable with. How high you can let it go before intervention is really up to your Ob - mine reassured me that she was happy so long as I didn't develop any extra symptoms.
I have had high BP for most of my PG AND edema the whole time but no other symptoms, and Bubbles has been happy (so happy s/he has decided there is no rush to get here) so my Ob has just "watched" it. I haven't had any meds or anything. The only thing my Ob has said that she wouldn't let me go the normal 10 days over my EDD. I have been booked for induction next Thursday. Although I was warned early in the peace that if it didn't stabilise she would make me stop working (this was when I was still working full time and studying). I dropped my hours and it was fine. I was also warned that bed rest was on the cards if I couldn't get it to settle. So no, I don't think induction is the only option, they should give you a chance to stabilise first with things like bed rest (hospitalisation to achieve this if necessary).
