Wondering... normal?

It's been a month and a day since I stoped bleeding with my CP and it was like a period but lasted 6 days longer than normal. They said I was 3 or 4 wks how long does it take for your cycle to start... i had sex twice unprotected after my bleeding stopped last month. Any possible way I havent started my regular cycle cause I'm pregant again? Or does it just take a while to come back? *Posting here and in am I pregnant*

EDIT.

Forgot to say I had to have xrays done on the 20th and I told them this and they did a test and it was negative but I had just had unprotected sex the last time on the 11th could it of been to soon?
