Trying to understand my vag

Audrey • married 💍 ttc baby #1👶

This is weird I don't really talk to people about this but I'm curious as to what this is supposed to mean..

Last night me and my hubby were doing the deed but we couldn't finish because it hurt me to too much. And when I felt there I'm swollen and squishy.. I've NEVER had this happen before. And we're ttc our first miracle baby any feedback?? Please and thanks
