On day 10 and Day 11 of my cycle, I started doing OPK test and got low fertiliy. How many days of high fertility do you usually get?
I started trying OPKs last month and on my first ever test got a peak fertility on day 13 and low fertility day 16.

High fertility days are very dependent on each individual person. I usually got 5ish days of positive OPKs but many only get one day or sometimes even less than a whole day. You’ll want to make sure you test from around CD 8 until you get your solid smiley.
I will say that I used a CB digital ovulation test for months and it only matched with my cheapie sticks one or two times. The month that I actually got pregnant it did not match.

update: Day 12 I got high fertility and today is day 13 and got peak fertility. Last cycle I had peak fertility at day 13. Though I wonder if my estrogen level is too low if I only have one day of high fertility

@happiness2020: have you tried the little cheap ovulation strips? There’s a reason why so many people prefer them. With cheapies, you see the progession of your LH surge (as lines get darker/lighter), whereas with CB, you’re just trusting that they’re interpreting it and relaying it correctly to you. Most people have a fairly short LH surge, but you’re fertile for a few days before that and a day or two after.

@happiness2020: Digitals aren’t really made to be read once ejected. If you’re wanting to see line progression you’ll want to buy som sticks. My favorite brand is the easy @ home brand. You can get them super cheap on Amazon and use them with the premom app.
