Losing my virginity but need advice on something.

I was about 7 years old and i was hanging off the monkey bars, i tried to do a flip and landed really uncomfortably on the chair that was under me, I started bleeding on my vagina. I go home and my mom gives me an ice pack or something, I cant remember that well. I don't know why I was bleeding, this happened about 10 years ago. I wasn't sure why i was bleeding and it hurt that bad, I'm a lot older now and I'm losing my virginity soon and I'm nervous that my body looks different because of this. My boyfriend is also a virgin and we are losing it to each other, should I tell him what happened cause I'm scared I might look different down there and I want to be up front with him. Or should I not tell him?
