I’ve never tracked ovulation. I have endometriosis and suspected PCOS been trying for 3 years almost to have #2..

Please tell me from here it might get darker? Period ended may 28 and I’m not exactly sure how long my cycles are. I know this isn’t a positive opk. I put in I have a 28 day cycle but I’m not really sure. Glow says if so I should’ve already ovulated. Yesterday I got a negative around 4 pm but didn’t know I couldn’t drink so much water so maybe it was diluted. Please anyone help me out. I’m desperately trying to Conceive.
