Is this discharge normal? Should i be concerned?

What is this? Only when i open the flashlight i see this yellow-green color!!I haven’t had sexual intercourse for 4 months. My period must arrive these days.

I had unprotected sex a few times, in february and in july. In february i took the morning after pill and saw green discharge the first time. (It was a bit darker as i remember) but then didn’t see it again).

i only had one partner all my life.

I don’t have any symptoms, it’s odorless, i usually have white discharge too but this light green/Yellow discharge concerns me.. Sometimes i wonder if it is the lighting or my paranoia.. but today i saw another “”sample”” dry on a paper towel and Even dried it looked greenish.. Even if i don’t always have it it’s weird seeing something like that.. and as i Said, i have no vaginal bumps, no itchiness, no swelling and no unpleasant smell. So What do u think it is? The last one is dried.
