Missed Period

I had sex two weeks ago, and during the top of the condom broke. We stopped and put a new one on, after that we showered and he penetrated me once without a condom. After that we didn't have sex. I was supposed to start my period on Friday, or today and so far nothing has happened. My CM is like sort of creamy and I think it's my period starting but it's not... I'm scared I might be pregnant and I can't have a baby.
