Am I pregnant?

I was reading that a clear stretchy vaginal discharge before period can mean that I’m pregnant and I’m scared? On the 15th of April is when we dry humped naked and he barely touched me with his tip(no condom)and it hurt but I’m not sure if there was precum? My boyfriend didn’t penetrate in me and he only came inside my panties and I wiped it off with a tissue but sill slept with my panties on that night. I’ve been experiencing a little bit of back pain,been peeing a lot and I think it’s bc I was drinking tea, stomach cramps(stopped yesterday) and my boobs hurt but they stopped hurting around 3 hours ago and I’m not sure if this is my PMs. I don’t know I’ve been ovulating for these past 2-3 days because I’ve read that it can be a sign of early pregnancy and I’m scared
