Ketones?

Candice • Hi I'm a mom of 2 a boy and girl. We had the up most surprise finding out we were pregnant with baby number 3.i just had cervical cancer and had surgery end if January was in birth control so surprise
So i had a Nst did a pee test today. No follow up with my dr until Tuesday. I asked the nurse about the pee test because my BP has been elevated she said all was good except there was a small amount of ketones in my urine. I know they are not necessarily a good thing. Anyone got info they'd like to share, issues? Inductions? Nothing?
