Cervical Mucus?

So before i start i know this is TMI but im so confused.

I woke up this morning, normal morning. I havent had sex yet today, my last sexual intercourse was around 6 yesterday night. When i went to use the bathroom i looked at my underwear and there was a HUGE puddle of wetness right in the middle it was creamy but the rest just looked watery and it smells exactly like cum, but when my boyfriend ejaculated in me yesterday he cleaned it out with a rag because it always tends to leak, when i laugh or even make a sudden movement. I was wondering if this was cervical mucus and why i have so much of it or if it was cum from yesterday?
