I let him cum in me

So the other night me and my husband were having sex, and it got pretty hot and heavy. I let him cum in me for the first time ever. However, we aren't trying for a baby. It was the day after my period ended. I figured at that point that my fertility level was pretty low. What do you guys think? Should I have anything to worry about?
