Opk question

So last month I started using opks and everything went great. I had a solid clear line when glow predicted. But this month I had 4 days where I had 4 very light lines. I usually feel myself ovulate because I have ovarian cyst the functional ones but they are kinda painful. Last month I had one just on my left side. This month I felt it on both but not as bad but the left side stopped about a day before the right did. This was the same days I had the light opks. I’m just unsure on wether I actually ovulated or not. Has anyone ever had this happen? Or does anyone have any thoughts on what might be going on.
