When to tell the baby daddy?

Hey ladies I need some advice, I just got a positive pregnancy test yesterday morning and it said Pregnant, but then took 2 more and got a like x instead of a + then took another one and it said not pregnant… idk which one is accurate, so I don’t want to worry him, like he’ll be excited but we’re not living together right now and we’re trying to work on ourselves. We’d definitely keep it and be wonderful parents weather we co parent or parent in the same household… I called the doctor hopefully going to be fit in tomorrow for a blood test and answers… do we think I tell him and maybe it’s a false positive, or do I tell him only if it’s confirmed positive?!
