Baby kicks

Elizabeth
I don't know why, but my baby just refuses to kick. I'm 25w6d and I'm lucky to feel him at least once a day, when I was less far along he would at least move twice or more daily but for some reason he just doesn't want to anymore. I'm beyond parinoid and I have a doctors apt on Monday but I'm not sure if putting it off is the correct answer. I just want him to be healthy and I don't think it's normal...but then again I just think I worry too much...
