I had a blighted ovum in January of 2012. I had a sac that measured 5 weeks when I was almost 8. I had a d&c my January 11 I think it was, af returned on February 14 and I found out I was pregnant again May 9, 2012 and gave birth to a healthy boy in January 2013. So I got pregnant on my fourth cycle after the miscarriage. Sorry to hear of your loss. They suck a lot. Good luck to you
