Should i tell my SO?

Hello✨
So i got two positive pregnancy test strips this morning so as the day when on i bought a clear blue and also positive , i dont know if i should tell my boyfriend yet since last time we ended up with a miscarriage on the 7 week of pregnancy he was so exited to be a dad and that horrible thing happened to us. Should i hold off until i actually see a heartbeat with this baby or should i tell him?
