Weird period 9 weeks after d&c

I FINALLY started my period after my d&c in March. It only lasted like 3 days then stopped. However, it started a day later after me & my fiance had sex. It wasn't spotting either. It was like a light period. Well it stopped after that day then I had a little bit of blood in my underwear a few days later. Not like light spotting. It was like a tiny period then it stopped. Is this normal??? Do I count this as my period still?
