Positive OPK 3 days in a row

Caroline

Hey everyone. I’m new to the OPK world and looking for some help. The <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says my peak was CD 12, and I have also gotten 3 positive OPKs after that (2 on CD13 and one this morning). Is this normal? And if so, what does it mean in terms of the timing of ovulation?
