GP says have lots of sex nice, your fertile, But he says nah

Sitting here (its late) and crying again. I see a GP today and during a routine Pap smear she says oh you better get home and have sex, a lot of sex your CM shows your very fertile. So I tell him that and we laugh and go to bed tonight ready and excitied to make a baby and he says "nah, I'm sleeping". WTF?
