Hi Sallymarie,
I'm glad you asked the question because it was running through my head as well. We have twins on both side of the family so I guess that genetically we'd have a higher chance. We did IVF so the embryo would have had to have split once it went back in. It would be so exciting to find out we we were having twins, either way I'll just be happy to have a live baby in my arms at the end of it. Our 8 wk scan is on the 19th.
