My babies have never got into a routine or anything until well past 30 weeks.
I don't know if it helps for those anxious about movements (it's the thing I hate most with pregnancy)
Not to expect to feel them every hour ect.
They sleep 90% of the time in the womb and you'll soon learn what is normal and what isn't for your baby.
My 3rd only ever moved first thing in the morning and last thing at night whenever I was laying down.
Would very rarely feel her during the day.
Where as my second was moving any time I ate. All night long. And a lot during the day
Unfortunately the experience for a lot of people in A&E with miscarriages are bad. I know there's nothing they can do but I've found from hearing everyone's experiences that they're so insensitive!
A doppler won't tell you anything really unfortunately and it can do more harm than good.
You can pick up your own heart beat and even the placenta and then think everything it's okay when it isn't. Even the heartbeat in general isn't an indication that something may be wrong.
And then on the other hand, you can not find the heartbeat and panic.
I'd try the number you're given again.
They should always get you in to check movements if you call.
