Baby kicks

Hannah • Hey my name is Hannah. I am a 27 yo SAHM 💙👶🏻 💙4/29/16 💙👶🏻 💙4/23/18
For the past three hours I have only felt the baby kick between 7-8 times when he usually kicks well above 10 times an hour. I called my doctor earlier (around 3) because I have been having watery bloody diarrhea all day and she told me to just rest and stay hydrated. My question is is 7/8 kicks still considered normal or should I call her again. I am 30 weeks. I am also high risk for preterm labor.
