Opinions please!!!

Viviana
So I had sex on my fertilization days 23 and 24 of April, it was without a condom at first but then with condom before he came. He swore he didn't inside of me, but I still went Sunday morning (24) to take the plan B pill. For that week, I was fine
Then Sunday may 1, a week later after taking plan B and had sex, I started spotting, and it continued until May 5, no cramps, only spotting, no heavy blood like a period what's so ever. Was this my period?? 
I was due for my period may 5, and nothing so far, I will be a week late tomorrow if no period occurs. 
Any ideas or suggestions? This hasn't happened before
