Issues being scanned

Natasha

Hello ladies, I’m currently 17stone about a size 20. I had a scan at 5 weeks and a scan at 6 weeks, both these scans detected a Bicornuate uterus. I went back today for my 7 week scan, baby had grown accordingly to 7+3 but sonographer was really find it hard to get a clear picture or to search for a heartbeat. Mostly due to my uterus but she also mentioned plus size ladies tend to not always detect a heartbeat until 9+ weeks.

Has this happened to anybody and what where your results?
