Whenever I don't feel movement I lay on my left side with my knees bent, she usually starts moving around then. I'm almost 25 wks and weigh 195
My boy is pretty still all day but at 10pm every night he kicks for about 10-20 minutes. So I think it's normal not to tell them all the time. I also went through 5 days of feeling nothing a couple weeks back.
My OB said to make sure I feel him move at least once a day from this point on. Doesn't have to be a constant thing.
I'm 26 weeks and we go thru a couple days of hard core movement and then a day of slow flutters.. at 23 weeks mine wasn't much of anything for movement... do you have an anterior placenta ? If you are concerned call your ob :)
