Diarrhoea before ovulation

Sw
Hi Ladies
I have recently started experiencing diarrhoea & cramps during ovulation. Took me a few months to realise it was related to my ovulation, as I thought I had IBS or something. Tracking on glow and adding my symptoms has helped me to figure out this trend. It starts 1-2 days before I get a positive on OPK. Does anyone know if this is a concern for TTC? Are these symptoms for endo
Thanks
