My boyfriend came inside of me but im on the pill

Help! My boyfriend came inside of me twice but I’ve been on the pill for 6 months and take it at the same time every day. We had sex 4 days after my period ended when this happened. I know that the pill is 99.7% effective with perfect use but I heard stories of women getting pregnant still. I don’t know if it’s just nerves but I’m getting nausea and have a lot of creamy discharge, like a lot of it. Will i be okay?
