Hi. I'm 39 weeks - I've been in for reduced movements 4 times, 2 of those times on the same day.
I also have an anterior placenta which means the baby can't always be felt.
The first two times were fairly straightforward (although they do sometimes struggle to find a heartbeat because of the placenta). The third time I went in the midwife wasn't great... She didn't really know what she was doing and didn't have great tact. She told me that if she was working in the midwife led unit she wouldn't take me so I should wave goodbye to wanting a water birth. I ended up going back again that evening having not felt any movements again (partly because I didn't trust the tests she had done, having been through it twice before and her admitting she didn't know how to use the machine!!) And ended up seeing another midwife, a sonographer, and a consultant that night. I asked all 3 wether this made me high risk and whether it would restrict my decisions when in labour.
In short, all three said no! They have found no reason for the reduced movements and have no concerns. They will obviously assess things on the day and can't promise anything but even the consultant said it could be my placenta affecting things and they wouldn't rule anything out.
I was so scared of going back that night and being induced (the midwife that day had said it was likely, but like you I didn't want that to cloud my decision to go back again) but they said unless you went in for reduced movements and there was a serious reason for the movements, you wouldn't be induced.
I hope that helps!! (I also got in a bit of a rant about my midwife which was very cathartic hahah!).
Good luck with the pregnancy X
