36+6 and decreased fetal movement

I'm so scared right now. Nobody is home, my husband is 2 hours away and I'm not supposed to drive anywhere by doctors orders and my baby hasn't moved that much today. She moved 2 times after breakfast and didn't make the 10 times in 2 hours. After lunch she moved once when I pushed on my stomach a little bit and when I used my doppler her heartbeat was fine but she only moved about 4 times. Now I'm laying on my side and she hasn't moved once. Last night I took a half dose of children's Benadryl but it should've worn off by now if it made her drowsy. I took a half dose of robitussin today for my cough and I feel so guilty. I've tried calling my husband but he's not answering.
