How to confirm ovulation besides bbt? any tests to buy out there?

aloha7

Hi! Is there any tests out there on the market we can buy to confirm ovulation? I know about taking your temperature but i am not sure if i ovulated hy taking my temps.. i want to do a test (not blood test cuz that requires a doctors requisition and thats impossible to get) but i mean any test we can buy?

Thank you!
