Ovulation while on period !?!

Monica

PCOS makes me question everything my body does. I wear a BB thermometer every night since December “Himama” it charts my sleep and reads my temp at my point of deep sleep. The 14th and 15 my temp dropped then spiked my chart read it as ovulation and then entering my fertile window but the 14th at midnight I started my period.

Then the 15th I noticed my CM was super stretchy

so I took an OPK test it came back positive any insight???

I’ve always been told you can’t ovulate while on your period so then what’s going on? I mean who wants period sex.... help !!!
