I won't stop bleeding???

So I had sex for the first time two nights ago and I bled (which is normal bc the hymen) and it stopped yesterday but it just started bleeding even more ???? I am freaking out. I have no idea what to do 
Edit: it was not my period. My body had accumulated blood and all the pressure of the blood and the clots made it come out all at once. Not very common, but it happens sometimes depending on how your body react to "tearing" your hymen
