Hey I'm only 16 and my left boob is really sore and hurts like hell. Its not because of my period because I've never had this during my period. Could it be a sign of pregnancy? The only issue is that its been a week and 2 days since I last had sex. Is this soar boob a sign? Help

One sore boob is unlikely to be a sign of pregnancy, it's more likely the result of a bruise or something like that.

In general, there are no reliable signs of pregnancy until you've missed a period and done a test.

Is having sex at 16 legal where you live?
