am i the only one?

la

so I had my period which was very light for me but I decided that maybe it was from the stress of ttc who knows. so anyways I'm on cd12 and am I the only one who is like my due date is September 1st and I'm a week and 5 days pregnant even though you haven't ovulated? I do this every month bol. and my husband always rubs my belly, kisses it and talks to "the baby" as if I'm actually pregnant idk maybe we are just a weird couple.
