Ovulation day 10??

Soooooo I’ve been trying to conceive for over a year with one miscarriage in October. I’ve mostly relied on this app for my ovulation . . Recently starting using strips. And they said I was ovulating day ten of my cycle (Jan 14) but according to the app I ovulate on Friday (Jan 19) all my strips since Monday are getting lighter . Was it possible that i ovulated on day 10 of my cycle? And I will of course keep tracking With strips but does it pretty much there’s no point in having sex again till next month ?? (To get pregnant lol)
