Ovulation?

Katie

How many days do you have a positive OPK? I have had a positive OPK for roughly 3 days now. CD 18 was pretty close, CD 19 was positive, and today, CD 20 was definitely positive, it was the darkest one I've had. I'm not exactly sure when I am actually ovulating, and I don't want to miss it! This is my first time getting positive OPK's, so I am unfamiliar with them. I need some advice. I will post pictures in the comments. Thank you in advance! 😁😁
