spotting

sorry for the tmi pic lol but I had sex on monday with my boyfriend. he pulled out but we didn’t use a condom. I’m on the pill and have been for about a month and a week. now it’s friday and I’m spotting. I didn’t have any blood when I wiped or anything but I’m curious what this could mean. my period isn’t due for like 17 days so I’m literally terrified lol. any help is appreciated. thanks! 💞

update: I’m also having weird discharge and I’ve been bloated today
