Pregnancy related yellow discharge??

Please help!! I’m ttc,

AF is supposed to arrive in 2 days. Clear blue early detection test (according to their website where you put in ovulation date, last period and cycle length) told me to only test Tomorrow at the earliest so I have not yet tested ..

I have been having symptoms such as super tender breasts and cramping that began 2 days ago (didn’t feel much today though, seems to be going away)

Recently I’ve been having some yellow discharge starting yesterday or 2 days ago

Could this pregnancy related?

Has anyone experienced this before period and ended up pregnant??

Thank you!
