Im late but I had PROTECTED !!!?

I had the day after my period ended. It was protected, we used a condom. I have had abd cramps for the last two weeks as if I was going to come on my period, I broke out, I was even bloated for a day but still no period. I took a HPT it was negative. I am now 6 days late. I have been under some stress but no more than usual. About 1 week before I was due for my period I had a pressure paid in my abd for about an hour it was tender to touch. Do you think I'm pregnant?
