I need help 😞

I had unprotected intercourse on Friday 3rd and my ovulation day was Saturday 4th. For one could I possibly be pregnant? My sex partner said that the first time he ejaculated a lot and I pulled him out and he said he ejacualted a second time inside me a little bit. And I also laid on the bed for like 2 minutes so could semen come out? And for two, today I noticed a lot of creamy kinda wet slimy white discharge in my underwear.Β
