White discharge

I’ve been having this white discharge that I can’t tell if it’s thick or sticky. I’ve been having it for 2-3 days now and it’s a lot. It feels like I’m spotting but it’s just discharge. Me and my boyfriend had sex on the day I ended my sugar pills and took my first pill of the month. We didn’t use a condom but he pulled out. Is this just a sign of my cycle starting up again or am I pregnant?
