Think I'm going crazy!

Hey guys! Think I've finally lost the plot! Lol! As AF came early we're in the rare position of my DH being off shift for every day in my fertile window!!!! We're at it like rabbits! And I've started freaking out (internally I don't tell him this) that if I move or stand up or go to the loo that I may lose valuable swimmers! I know it's stupid and I know it doesn't work like that but it's in my head and it's not leaving! I officially have the TTC madness!
