Period blood or breakage blood?

So this morning I found myself bleeding. I thought it was odd because if it's my period it's 14 days early. If it's not, the last time I had sex was June 27th and he didn't have the condom on for one pump in me and it was dry before it went in. After he came out we out a condom on immediately. I'm not sure if it's breakage because I was told it takes about two weeks for the sperm and egg to connect. So is this period or should or am I possibly pregnant?
