No bleeding?

Miranda

So this is my first pregnancy, I’ve read plenty of posts of women experiencing bleeding early on and I had a friend who bled at one point of the first few weeks of her pregnancy. My question is it normal to not bleed during the first few weeks? I took 3 tests cause I didn’t believe the first two and all came back positive. I haven’t had my first appointment yet but I’m just worried since I haven’t experienced any bleeding.
