sex position while conceiving?

This is probably a stupid question, but has anyone found that their position during sex had an impact on them conceiving?
While my husband and I have been TTC, I have made sure I was on the bottom when he finished, because... gravity lol
But today we had a little foreplay in the shower that ended up going too far before making it out of there.... so he finished while we were standing..... I know the sperm supposedly goes where it needs to go, but i was just wondering if anyone has conceived in other positions?
