Red watery discharge?!? Confused..

Emma

So I need your advice...

My period is not due until 18/1 but I went to the toilet about half an hour ago wiped and there was red watery discharge, not full on period kinda blood...

So I’m confused... I am also in my ovulation window right now too and I have been trying to conceive for 22 months now... I never normally have this between periods...

any advice welcomed!
