not pregnant?

My boyfriend and I had sex on Feb. 18th. He wore a condom. After ejaculating every time, he went pee. A few hours later he stuck in half of his penis into my vagina. He did that twice and that's it. After that he just took it out. He never ejaculated inside of me. I have been on the combination pill for four months now. I take it at the same time everyday. I had some light spotting on the night of Feb. 28th. This was the day my period was due, I think. I realize my body is still adjusting to the pills at this time.  I put a pad on before going to bed. When I woke up the next day, the pad was entirely full. I bled through a few regular tampons and a few supers and pads. My last day of bleeding was March 5th. I was also very stressed and ill during this time. I heard that can affect your menstrual period. 
Does this sounds like a normal period or implantation bleeding? Does it sound like I'm pregnant? 
Most of my peers agree that it's a period, which I was hoping for. 
I start my period again next week. 
I am in need of some reassurance. Thank you ladies.
