please help i’m confused 😭

So i took a ovulation test a few days ago and it was pretty dark and then started to get lighter and lighter, i ovulated on the 14th i’m pretty sure so i’m around 5DPO. But today i noticed i’ve got a bit of egg white discharge that’s not super clear as it has a small milky colour too it and then some parts are clear. What’s going on does anyone know 😭 i had sex last night and didn’t use protection so could it just be his semen coming out?
