Sex with condoms

My boyfriend and i were having sex on an afternoon of...last week? I was riding him and i noticed that it has gone for a lot longer than it did before so i was beginning to worry if i was doing something wrong -but he was totally enjoying it. We later stop and when he pulled out, we found out that he already came and the condom kinda rolled up. We’ve been stressing about this for awhile now and my period is next week, i’m too anxious to wait for it to see if it’s late. Anyone have any opinion???
