Bleeding in early pregnancy

I took a few tests yesterday & they were faintly but definitely positive. (Period was supposed to start in 2 days) Today, me & my fiancé had sex & during he told me that I was bleeding. Bright pink with some brownish clots with a tad bit of bright red. I’m cramping a little as well but I know that’s common in pregnancy, with my last pregnancy I did cramp as if I was about to start my period. My question is, Is bleeding common in pregnancy??? I didn’t have this with my last one.
