B.P.
If your gut tells you to call the doctor, please call the doctor. A baby that is over-active in movement may not necessarily be normal.
I am a memeber of varios stillbirth support groups (I had a stillborn son at 32 weeks gestation last year) and there are many Moms out there who said that they wished they had gone to see the doctor when their baby was not behaving "normally" (IE: more movement than usual; less movement than usual).
My intent is not to scare you but to caution you that if something feels out of the ordinary and your gut tells you to see the doctor, PLEASE go see the doctor.
Good luck to you :)
