My Girlfriend Is Having Implantation Bling Why Has Anyone Had Implantation Bleeding With A Past Pregnancy And Had A Girl?!?

Has anyone had implantation bleeding with a past pregnancy and had a girl?!? - my girlfriend is having implantation bling why

I am 6 weeks pregnant with my second child, no bleeding with my daughter. I read somewhere that some say bleeding during early pregnancy (implantation bleeding), as a rule, you have a child. This is also true with many women. Nobody implantation bleeding in early pregnancy and have a child? "

Thank you!
