can i be pregnant?!?

21 days ago me and my boyfriend were messing around but did not have sex. But I am afraid that when he touched my vagina he had pre-come on his hand. I am on the combination pill and I take it every night but sometimes four or five hours late. This happened on the last day of my period, now my boobs have been a little sore but I have taken many tests and they were all negative. Is there anyway I'm pregnant?
