Bloody discharge

I had a surgical abortion about 3 weeks ago. I only bled for one week. This morning I had a little blood and thought I was going to start my period. After that nothing all day now it's 3 am and when I just went to the bathroom I had blood again, but it was more like a bloody discharge. Is that normal? Seems kinda weird to me... my boyfriend is asking if we should go to the doctor?
