Thick white discharge came out after sex

I just had sex with a condom. We both came and then when he pulled heaps of thick cum like discharge fell out of me. We are pretty sure the condom didn't break because there was so much of the discharge there would have to be a massive hole in the condom for that to come out. It was like all the discharge was sitting inside of me and he "plungered" it out of me. Is this normal? Should I be worried and take the morning after pill?
