Do I have pink eye?

Earlier today, my eye randomly started hurting. It felt like something was in my eye and it was very sore to touch. I thought I had a sty but when I looked in the mirror, I noticed that my lower eyelid was really swollen and that I had a lot of random mucus accumulating from it once I started rubbing it. A few hours later and the swelling went down. But now, my eye is still mucusy. THERE’S NO ITCHING, but my eye keeps accumulating mucus and it keeps feeling like I have something in my eye. Not like how it feels when you have an eyelash but how it feels when you have mucus in your eyes in the morning. Am I gonna have any surprises when I wake up tomorrow? 🙄 I’ve never had pink eye so I’m wondering is this how pink eye starts?
