Thank you for your query.
Firstly, 10 - 15 movements per day is absolutely normal.
Normally, after each major meal, say breakfast lunch and dinner, your wife should lie in the left lateral position and count fetal movements.
More than 10 per day is normal, so please dont worry.
has no effect on fetal movements.
Also, the medications prescribed are okay, as long as there is an indication observed by your obstetrician for risk of preterm delivery.
