Gender by heartbeat myth debunked!!!

Ok I keep seeing posts about gender by heartbeat. I just wanna let you know it's totally just a myth!!! My babies heartbeat was always in the 180s and as I got further along went to 160-150 I though hey maybe it's a girl! 😃 NOPE!!!!! It's a boy! I asked my dr wow so why was his heartbeat so fast?! He just laughed and laughed and laughed and said have you been googling?! Lol 😂😂😂😂 he told me there is completely no medical backing up the myth and it is literally just a waste of time!! So don't get your hopes up due to heartbeat Becuz it's just not true!
