Ovulation

I have a question.. So, you know how glow has your fertile week, it's green and has the percentages (which I'm assuming the highest is the day you're due to ovulate). And they say you get a positive opk 12-36 hours before you ovulate. So, when logging, I click "yes" to a positive opk and it's usually 2 days before the highest percent day. But then glow changes the fertile week and makes the positive opk day now the highest percent day too and shortens my fertile week. Why does it do that? Should I just say "no" when it asks for positive lh surge when logging?

I'm curious about that too. Doesn't make sense to me.

Your highest percentage day is not the day of ovulation it's the day before ovulation. The egg only survives around 12 hours after release so it actually increases your chances of conception if you have sex the day before you ovulate. That way the sperm are ready and waiting when the egg is released.

Ohh. Okay. So when I get the positive opk, it changes that day to my highest percent day and the following day is ovulation. Lol got it!
