Positive Ovulation Test while at work

Rabiyyah • Over 35 and trying to give my husband a son.
While at work I took my Ovulation test and it's positive. My husband and I are both on our jobs. How long will I be ovulating? I tested last night before going to bed at 9pm and it was negative. Should I leave work now or will I be still ovulating when I get home at 5pm?
