34 weeks failed nst but passed bpp?

So baby girl failed her nst today and didn’t have any accelerations in her heart rate on the 20 min test. But dr said she passed her bpp ultrasound and was practice breathing through the entire ultrasound. Obviously this has got me worried. I have two nsts a week every Tuesday and every Thursday and have an ultrasound every Thursday as well being high risk with hypertension and history of preterm labor. I’m scheduled to be induced at 38 weeks on the 30th of this month. Any other mommas have this happen??
