Is it normal to bleed twice?

My friend (19) lost her virginity a few days ago and has questions. One of them being, is it normal to bleed the second time you have sex too? I couldn't answer so I figured <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> could help. She said she bleed the first and second time. And she said there wasn't a problem with it being too rough or lubrication issues. Could someone answer her question?
