Hi , My last menstral cycle was December 6 . I had unprotected sex around the time I was ovulating . My period was due today . But , I had brownish , w/ a slight pink reddish blood 3days ago . Im still experiencing this . Could I be pregnant ?

Well... there could be a chance... but it sounds like you aren't because you're having a type of period... but to be sure, buy a pregnany test. They sell them Wal Mart if you can't go anywhere fancy :) good luck!

It is far too early to test, you have to wait till you are at least 10 days and 14 is better, days late.

But yes, the spotting can be a sign of it, but also signs of infections or other issues.
