Hi. I had my period on 7th Dec I had sex with my husband on the 18th & 20th of Dec - expected ovualtion date was 19th Dec... Today (Dec 22) I experienced some light bleeding when I went to the bathroom - it is a light brownish color & mostly only when I wipe. Could this be an early sign of pregnancy?? When do I take a test as my period wasn't suppose to come again until Jan 3rd 2011.
