Late ovulation??

Can metformin cause late ovulation? I also have PCOS. cd 18 and all flashing smileys for the last 6 days on clear blue, no peaks yet. as you can see I had two days of peak, but they are very weak and technically negative. I’m having a lot of bloating and cramping today, pretty significant bloating to where it’s almost painful,so I’m hoping that means my body is trying to ovulate again. Thoughts? Comments? I realize I didn’t LH test correctly some of the days. Thanks.
