What is this discharge!? pic tmi

TMI… I am on birth control ( sprintec) and I’ve never seen this until a couple years ago…I have no irritation, no redness or soreness and no smell. it’s hard to keep track of because I don’t see it all the time it’s random. I could wipe one minute and see nothing and the next this! I hate it. it looks like wet toilet paper and it only seems to come the week or 2 before my cycle or maybe a couple days after sex but I’m not sure? no itch no burn no anything!!!

it an be a normal discharge for you
the only way to find out is get a sample tested
