After sexy time

Hi ladies, i was just wondering. After me and SO have sexy time, I put my legs up the wall for 15 mins. But when I stand up... cum drips out.. Is this normal and will it affect my chances of TTC. This month I'm going in blind, I'm not using OPK or listening to glow. I had ovulation pains yesterday evening and starting today so I'm going by that and seeing what happens.
