To call or not to call...

I'm 25 weeks. Yesterday I ran into my husband belly first into his behind.. i was moving forward he was moving back and it was pretty hard. I wasn't worried but then I felt the baby moving very little and it started to make me nervous, around 7:40 last night I felt her move twice and then I didn't feel her all night. Which is not normal, she is usually very active during the night. I woke up when my husband went into work which is a time when she is usually very active and nothing. Now I have felt her move quite a few times this morning but still not as much as normal. Should I call the dr or just hold off?

My dr. has always told me that if I dont feel my son 6 times within his most active hour that I should call.
