Opks and PCOS

I'm getting a little discouraged and really not trying to be. This our first time doing opks and 1 month really <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> with having pcos ttc#2. box says these are all negative😔 I'm on CD 19 I believe (cycles are irregular), felt some light cramping last night on my left side and I took an opk still saying negative. I want to keep testing but I every strip I keep hoping for that dark line! Need some advice and some baby dust☹️
