Canceling NST appt

anony mouse

I have 3 appointments next week. One with my OB, one for a BPP, and one for an NST. 3 days in a row. Would it be bad to cancel the NST? I have been having them weekly and baby has been great at every one. The BPP, from what I understand, is an ultrasound while they basically do an NST. My 6yo has a half day the day of the NST and it's going to be really tough to make it to pickup on time and my husband has been taking so much time off due to all the appointments that I don't want to stretch him too thin. His boss is very demanding.
