So two days ago I took a clear blue digital ovulation kit and it told me I was at peak. Now two days later I take it again and it says the same thing. I thought the peak ovulation was only for two days? Is this normal? Very confused because my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says today should only be 8% chance of pregnancy :/ hmmm any suggestions.
