Ovulation question..

Heather • Mother, wife, soldier♡
Ok so my husband and I just starting trying to concieve. Well he is a paramedic and works 24 hour shifts and I read that you usually ovulate 12 to 36 hours after your positive test. I got my positive ovulation test this morning and he has to work a 24 hour shift tomorrow. Is there still a good chance that we can concieve this cycle if we BD tonight ?
