ovulation kits?

Hey everyone! my husband and I have been ttc for a year now. We haven't really been using anything other than this app to determine when I am ovulating. I have a very regular cycle and always have the "fertile discharge" around the time Glow says I am fertile. But, we are 21 and 22 years old. Being that we have not gotten pregnant yet worries me. Yes, I've already made an appointment to be seen and make sure everything is ok down there. But, anyone have any opinions on ovulation kits and is it worth trying?
