Opk help!

This is my first month using opks and I’m confused. My cycle is 15 days late today. For the last 2 years I’ve had a cycle every month between 35-49 days long. My last cycle was August 25th til September 1st. It was the weirdest cycle tho because I spotted from August 21st-the 24th and even when i felt like it was actually on it still was light. My friends talked me into ovulation testing so I’m trying. I started having cloudy EWCM around 10/9 and it jus got clearer and stretchier as the days went by. On 10/11 I started having mild cramps and on 10/12 the cramps intensified along with the EWCM. Premom app also says that 10/12 was my ovulation day so🤦🏽‍♀️. So I figured this must be ovulation since the strips are so dark! I am still slightly cramping but the EWCM has dried up. TMI😩but My nipples were slightly sore the last couple days but they feel more sore now🤔. I tested today and the line is the darkest of them all. Am I really ovulating or is this just the pcos? Any advice is appreciated 😩❤️
