I had unprotected sex on the last day of my period. I took an ECP right after it in a few hours. Now my period is over 50 days late. I did a test 10 days ago and it came out to be negative. I have been worried sick. Am I pregnant?

PS: He did not come inside me. I was bleeding through the sex as it was also my first time but since it was not at all rough I very much doubt that it was my hymen that broke. Just my period flowing. I had withdrawal bleeding 4 days after it. So it was basically like my period extended. Also, i am having PCOS.
I don't feel any pregnancy symptoms as well. Only a couple of days back I had something of a pain in my left ovary. I do have ovulation pains as well.
Does it mean that I did not ovulate at all for one cycle?
