Ovulation kits?

Question

What cycle day should I start using the opk? Also which ones do you ladies prefer, and why?

Answer

I usually don't start testing until cycle day 9, but I know that I don't ovulate before that. Everybody is different. You might want to start right when af is done just to know your body better. I love the wondfo kits from amazon. They work well and are fairly cheap.

Answer

Thanks!
