Am i pregnant?

So i had unprotected sex during my fertile window, i took a morning after pill same day, i got my period but it was quite painful than usual and so much clots.now im done with my period, my body is acting like im pregnant, my boobs are heavy and hurt, i have sharp pains in my abdomen im still bloated and im spotting. Yeah im scared to take a test. Could i really be pregnant though?
