No pregnancy symptoms, just have slight cramps about twice a week, two headaches, and occasional sore boobs. my period's due this week, am i pregnant?

We do not Guess: First, it takes about fourteen or so days for the pregnant female body to know it is pregnant. Thus any symptoms before these fourteen days have passed are not in any way pregnancy related. I am sure you know this simple fact, but perhaps have forgotten it. Second, we do not guess at diagnosing pregnancy. If your period does not arrive in a week then it is time to get a pregnancy test.
