any advice

So AF came on the 19th. This is my second period since being of BCP. I guess my cycle is pretty regular being 28 days on the nose. I just bought a ovulation 20 day kit yesterday. I'm so new to all this but I thought I would try something easier to figure out the ovulation day rather than the calendar method. Any advice on anything else that I should do on top of the ovulation kit?
