I am almost 7 months pregnant about 30 weeks and I am not feeling much fetal movement. I feel fetal movement?

everyday about 5 times but i don’t think that is enough according to the rule that ive heard the baby is supposed to move 10 times within two hours.also I have asked my doctor and he told me that i am very overweight and that this is my first and that is why I’m not feeling much fetal movement.Do you have another opinion based on your research,past experiences,or knowledge????? I’m worried!
