It could just simply be part of cramps, but if the pain gets to high your OBYGN can do an ultrasound.

I get stabby pain around my left ovary during my cycle usually. ... the odd part is that due to PCOS, I don't actually have a left ovary anymore.

I do but I also have endometriosis on top of having PCOS… that could be something to potentially look into, as endometriosis typically can’t be seen on ultrasounds ❤️

I get that standby pain on the left side that you’re talking about but it’s from my IBS. The intestines are there and it always gives me cramps. It is very hard for me to distinguish between the PCOS pain and the IBS because they’re legit right on top of us in our bodies. I don’t know if this helps you but it’s just my experience.
