Ovulation question

Ok, so my last positive OPK was January 3rd. My next predicted fertile window was supposed to be the week of March 24th (I have crazy periods) but my CM was very wet the past couple of days so I decided to do an OPK and the cheapie came out positive so I used a digital and it also came out positive, but when I entered it into glow it didn't change my fertile week. Wouldn't this week change to my fertile week? Also, January 3rd was CD 58 and today is CD 24! Anyone else have crazy O days like this? Makes it very hard to track!!
