blood pressure 40w2d.

so i had an appointment earlier and when getting my blood pressure checked the first time it read 140/85. so she switched arms and it was 122/80 something i can’t remember exactly what the bottom number was. when my doctor came in she asked me to go for a NST tonight, i’ve had two previous NST’s for decreased movement but he was fine, just stubborn lol. i’ve never had an issue with my blood pressure, but i’ve noticed i’ve been swelling more than usual lately. i’m also scheduled to be induced monday at 12am, so my question is, any idea why she would ask me to go in for another NST? also my appointment was at 1pm today, she said to come in for the NST at 7pm tonight.
