Panicking!!😳

Ok ladies, here’s the situation. Me and the boyfriend have been knocking heads for months now, so I put into motion plans to move (out of state) which he is against and upset about.... well I’ve just discovered my period is a week late! Took a test, it was negative! But no period as of today! NOW, here’s the psychotic part: I had my tubes tied years ago! Him wanting kids is not an issue... but baby Jesus I’m losing it because I don’t know for sure if I am pregnant! And I can’t even get a drank to calm my nerves! I’m acting as if I am until it’s confirmed positive or negative! So I don’t know what to do because my house was being put on the market at the end of February... have mercy... any advice would be appreciated
