I am usually never late or irregular, or at least haven't been in the past few months. I was supposed to start my period 3 days ago...still hasn't come. The only symptoms I have are sore boobs ( just on the under side) and every morning I cramp like I am about to start, then nothing happens. The cramps go away after a few minutes. I know I could just take a test, but I have been extremely busy all weekend and just curious what others have gone through.
