Kinda Spooked Is it left over Pre-Cum?

Yesterday me and my boyfriend had sex. We used a condom then I got wild and took it off. He didn’t ejaculate inside of me he says. But he also Pre-Cums a lot. This evening when I looked at my discharge it was sooo different. It was like a film. I investigated further and it was a weird clumpy consistency in my fingers. It didn’t stretch and was like gum or drying glue. I did take an emergency contraceptive earlier. Was it Pre-Cum? I know it can’t be an STI I’m sure it’s not a yeast infection either. I did wake up congested and with a runny nose this morning? Am I just being paranoid?
