Positive ovulation test for 3 days!

Cyndi • I am married to a truly amazing man who I am proud to call my husband and best friend. We are expecting our 1st baby!
I have PCOS. I have never had a positive ovulation test. And now the last three mornings I've taken tests they have all been positives! What does this mean? And when do you have sex if you ovulate for days in a row? First day, last day?? (We only had sex on the second day I got the positive ovulation test).
