4th NST this week...

So tomorrow I have to return to the hospital to get my 4th NST of the week and second BPP.. I had to repeat NST today since the baby failed it yesterday and the doctors were slightly concerned, he then failed today even with all the interventions (buzzer, juice, position change etc). So they had me do a BPP and he got 6/10 so now I have to return to repeat both tomorrow again. Should I be concerned about this? No one at the hospital seems overly concerned and said it’s just formality but I feel like 4 days in a row is a lot of monitoring? Anyone have experience with this??
