Question!

So me and my fiancé used pre seed for the first time last night!!! But I think some of it came out after we had sex. It didn't seem to come out till I stood up. I'm pretty sure it was the preseed because my fiancés leftovers as you could say come out immediately . My question is, is it normal for some preseed to leak out afterwards? Or am I just thinking it was some of the preseed? I used the 2nd line on the applicator.
