Non stress tests

Britney

Went to my dr appointment this morning and they informed me now I have to do non stress tests weekly because of my weight. I'm 34 weeks and they have never brought up my weight before. I've always been on the heavier side and sadly I have gained about 30 pounds this pregnancy so far. I'm a pretty active person I just love to eat especially now that everything seems to taste better! Should I be nervous?
