Hi Poodle
I had to google "perinatologist" as it's a term I'd never come across, I just had a "consultant"
I'm guessing that you are not in the UK - if you are, it must be a very posh hospital
I seem to remember I was switched to fortnightly scans around 27 weeks. I would suggest to you that you go to the 28wk scan as scheduled but ask them to repeat the dopplers to compare to the last visit - to be honest, I'd be surprised if they didn't do this as a matter of course. If the notching is still present, tell them of your concerns regarding long periods between scans and ask if you can have more frequent appointments. It could be that the notching isn't too severe, but they should explain this to you.
As for something happening to your baby, as I've told others before on this thread,
trust your instincts. You should be feeling your baby move, so keep daily notes on when/where, so that you have a comparison. Ask your perinatologist (love that word now!) what you should do if you have reduced movement, do they want you to contact them or do they want you to report to maternity triage for a heartbeat check? And have your hospital bag packed now, rather than thinking that you don't need to bother until 36weeks onwards.
I'm not trying to be alarmist, just trying to make sure that you are prepared. And then hopefully you won't need any of these preparations, you'll carry to term and wonder what all the fuss was about
PS. I was 40 when I had Andrew!
PPS. Something someone else mentioned, can't remember if it was on this thread or not, but it struck me as obvious afterwards ... This other person was told to make sure that they stayed really hydrated during their pregnancy, as liquid intake can affect bloodflow. I tried to give blood once about ten years ago, and my blood was really slow coming out, like treacle! I don't ever feel thirsty, so I don't drink much (certainly not the 2 litres/day that's recommended). And this could have contributed to the arterial flow problems. I've never had a conversation with a medical professional about this, but it's worth considering. Whilst you drink a cool glass of water
