NST didn't go well - contraction stress test

Went in for my regular twice a week NST this morning. She has been rocking them but this morning her heart rate went down three times. They sent me to L&D for a longer stress test. No issues with that but I've  been given the option of 1) inducing now 2) doing a contraction NST... Which if she doesn't pass they induce
I was so not prepared to have a baby today.... Anyone had a contraction NST (where you get pitocin to see how baby's heart responds to stess of contractions)?
