Non Stress Test 39w4d

Hello fellow soon to be June Moms-
I had a 39w appt this past Monday (6/6/16) - my doctor sent me for a non-stress test (NST) cause bc my bloodpressure was slightly elevated, as well she did blood work & urine (as usual) 
The NST was fairly simple. The baby is doing absolutely fine 🙏🏼 though Everytime the doctors & nurses came to talk to me they made me very anxious & nervous that my blood pressure would go up 😳 I told them that they are making me feel very uncomfortable & nervous. They leave,
Blood pressure taken again and it's normal. We went through this process about 5 times and each time they spoke to me it went up, they went away back to normal. 
Fast forward to today, all my blood work & urine analysis came back normal. No signs of protein in urine or any indication of preeclampsia. My doctor called me not to long ago stating that she wants me to go twice a week for non-stress even though everything checked out ok. I expressed to her how I felt when I went for it earlier in the week. She says that it is so close to my due date and she recommends it.
I asked her does she suspect something is wrong with the baby they she wants me to go twice a week? She said no, but she wants to make sure that the baby doesnt get stressed. I will and have done any & everything to have a healthy pregnancy & make sure that my baby is safe. I have no problem going to the doctors to get tests done but i just don't feel this is necessary.
Has anyone else gone for NST twice a week & if so, why did your doctor send you?
Feeling very anxious
Thanks for reading😊
