Definitely go to the hospital and get looked at. It sounds like you are miscarrying.
I had a period like it was my normal one my last pregnancy and I miscarried. Go get it checked out hun
If it's a flow I would go straight to the ER!!
You should see a doctor, if it's flowing at all it should be checked, many things can cause it, but best to get checked!! Good luck hun!
Its reddish brownish and medium flow
Is it red or brown, how heavy of a flow?
