Need some reassurance

So my boyfriend and I were messing around the other day and about to have sex. We always use a condom. This time I got the condom and started to put it on wrong and the condom touched the tip of his penis before I realized. We were so in the moment that I flipped it around and put it on him. I’m pretty sure I wiped the end off that had actually touched his penis before we started having sex. Anyways, could there have been precum on the outside of the condom that would get me pregnant? I am on nexplanon birth control but we use two forms of protection just to make sure we are careful. Any thoughts?
