fetal heart rate at 25 weeks

K
Hi ladies so my baby's heart rate is usually 145-150 bpm. I have an at home Doppler and her heart rate is 130-140 bpm. I am on meds for high blood pressure and I go back to my perinatologist in a week. My baby is also having a lazy spell these past few days and hasn't been moving much. Is this something I should worry about?
