Nose was head-butted 3 weeks after septoplasty/rhinoplasty and bled. Is this bad and will it change the shape of my nose?

It's been 3 weeks since I had my septoplasty/rhinoplasty surgery. I was sitting with my boyfriend when he accidently head-butted my nose. I felt a crack and immediately started crying. It felt sore and I put ice on it and noticed a tiny bit of bloody mucose coming out of one nostril. Is my nose damaged at all? I don't see a change to the shape of it but could it change over time because of the hard knock? And what does the blood mean?
