I'm new to this site and I'm hoping to get some help. I experienced a m/c in October '11 (my third pregnancy and second miscarriage), and recently felt like I might be pregnant before my period arrived last week (12/21). I went for blood work on 12/20 and dr said it was on the border of negative and wanted me to come back for a re-test in a week or two. When the dr heard I got my period (or what seems like my period), the office said don't worry about coming back to get re-tested. If it was my period, it was right on time and lasted 5 days. I finished my period on Sunday and I still have feelings every now and then that I could be pregnant. What should I do?
