Ok so I got pregnant on August 5,2012. 3 weeks later on August 26,2012, I started having extreme cramps and bled bright red. I believe I miscarried. Today is September 15,2012. I started my period, at least I think. I bled for half the day red and then later on that night around 6:00 I started to bled brown (old blood) I asked the computer but it keeps saying I am pregnant or its implanation bleeding. I haven't had sex since I got pregnant last month on the 5th. Im wondering, could this be from the miscarriage I had or could I have been pregnant with twins and lost one of the twins and not the other. (twins runs very heavily on both sides of my fiances' and my family) please if anyone can answer this for me it will be greatly appreciated! Thank you!
