OK so I had my last period on Oct. 10, 2013 and now it is Nov. 25, 2013 and still no period. I have taken 2 test (both could have been too early) but both were negative. In the last two weeks I have been having symptoms such as:
lower back pain
I have been having unprotected intercourse about 3-4 times a week since my last period, could I be pregnant?
