goodmorning, i have been ttc for about two months now. I m/c with my last pregnancy in October 2008. I have been charting and tracking my ovulation but it varied with each charting. With my first preganancies I got pregnant havign sex on the last day of my cycle, so I tried it again- my cycle started 1/12 and i had sex on the 14th and 15th. Yesterday I had some brown discharge and cramping with lower back pain. I dont want to get my hopes up, but its hard not to.. had anyone experienced implantation bleeding this soon after sex?
