Advice after doing the dirty deed!

Hailie • Young girl living in a small town. Me and my husband are happy to be TTC and starting a new family. 💓
So I told my and my husband's family that we are TTC. They are all very excited and supportive. They are also shoving all these different tips down my throat. There is one thing I'm worried about. So after doing the baby dance should I stay laying down for a few hours? They told me I shouldn't get up or go pee because it will cause the sperm to come out and I wont get pregnant. Please help.
