Firstly, congratulations on your pregnancy!!
My guess is every hospital is different but I'm pregnant with my second high risk baby (first is now nearly 2).
I can only tell you of my experience which may prompt some questions for you to ask
-I also had scans at 12 then 20 weeks so seems normal. But I'm also getting scans at 28 and 36 weeks to check on baby and growth so this may be the same for you
-I am part of a specialist midwife team and am seen 6 weekly by them and monthly by a consultant clinic.
-these appointments tend to be split into: my health, blood pressure, signs of preeclampsia etc and then baby's heart rate, growth etc. So I am monitored as much as the baby
-I am asked to take my blood pressure regularly at home and take aspirin to reduce preeclampsia risk
-as I am high risk my labour won't be in midwife led unit but in the hospital labour ward. I know they also won't let me go passed 40 weeks so I'll likely be induced again
-if the baby shows slowing growth (this is likely due to my health condition) then they will probably induce me at 38 weeks
-once I knew I was being induced I was offered a referral with the anaesthetist team. They advised an epidural once on the drip to be induced. Last time my epidural failed so I have a further referral now and will want to know what plan b and c are in case it happens again
-I also know I'll likely be kept in for 48 hours post birth to check everything is ok
The above is a snapshot and specific to my health issues but hopefully may lead to ask some questions.
Lastly, just to say that I felt very cared for throughout my last pregnancy and this one. My induction was painful but not any more or less unusual than someone else's. It was more extra monitoring and a more medical birth than if I wasn't high risk
Good luck!!
