Opk newbie, need some help

Kimberly • Married 9/21/12 💍Mama to baby B 5/27/16👶🏼 Baby #2 due January 2019
Good morning all ? let me start with a brief background. hubby and I have been trying for about a year and a half now. I have a thyroid issue and pcos, periods were very irregular. The last three cycles came on time and on their own. This month I bought myself a 50 pack of opks. I had what I thought was a positive on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. The test line was darker than the control line. No other symptoms accompanied that so I continued to test. Well this morning I got a clear as day positive and also have ewcm. I'm thinking today is my positive and the 24th was not? Sound about right all???
