Small period or....

Hey everyone, first post in here!

So me and my partner have been trying to conceive since February, had some tests done at the hospital and was told I have polycystic morphology of the ovaries ( no clue what this means as was given no explanation!)

Blood results normal and show that I do ovulate, yay!!

Last week I had a 3 day “ period “ which was 12 days early, period due today and no signs at all?! Any ideas???

Thanks in advance!
