Favorite ovulation tests??

Hi there! It’s a far shot, but my husband and I are ttc our second child before he leaves for a job assignment overseas. We only have one month of ovulation to try, but if we get lucky he would be back before baby is born!

Anywho, I’d like to maximize our chances, so what’s been your go-to ovulation tests? Why did you like them?

Thank you so much!
