Question

I had a miscarriage 3 weeks ago so that last couple days I Ben cramping and my boobs were hurting and I just thought it I was ovulating then yesterday morning I was bleeding like my period so I thought it was but I was having horrible cramps very strong I never had them like that then by the end of the day yesterday the bleeding slowed down and was brown and little blood clots and today it completely stopped ? Was it a period ? It was only one day or is this apart of my miscarriage
