white stuff coming out of vagina

Me and my boyfriend were laying down and he went in to give me head. Then he was like eww what that. And I'm like what what omg what. Then I seen a bug glob of white stuff coming out of my vagina. My boyfriend is now spooked because he said it was moving like jello. I cleaned my self up And about a hour later, we decided to have sex when he looked down there was more white stuff. I was saying how it's possibly discharge but it's never been that white, there's no bad smell to it and I'm not itching. I read something and it said pregnancy or sti. Should I be concerned
