Is this normal?

So I’ll be 37 weeks on Thursday and I just had an ob appointment today and now they want me to come in twice a week until I have my son. So on Tuesdays I’ll be coming in for a non stress test and to check the amniotic fluid levels and then on fridays just for a non stress test a second time. This is my second pregnancy and I didn’t have to do this with my first so I’m just confused.
