The past months I've been having intercourse with out any protection. Right before the time I was expecting my period I experienced two days of heavy heavy bleeding and them it stopped right after the second day. My period is never heavy and never last two days. Then about two days later I started bleeding in the morning for a little bit them it stopped again and never came back. So is it a period or pregnancy.

There's no way to tell you what's going on, it's impossible to diagnose over the internet.

If you believe it's a possible pregnancy then wait at least 2 weeks after your missed period (if this bleeding is in fact not a period) and test using first morning urine.
