My Boyfriend And I Tried Fisting In My Vagina For

My boyfriend and I tried fisting in my vagina for the first time. He did not take his time and went very deep with his fingers but did not get his fist in. I am now bleeding profusely with large blood clots. It is time for my period so I dint know if that is where most of the blood is comi.g from. Could he have opened my cervix to make the blood come out faster?Should I go to the hospital to check for any damage?
