I couldn't tell at 8+5. I don't think it is possible by scan at that gestation. Even the heart rate isn't much of an indication until your further along. I would be taking guesses based on timing of intercourse when you fell pregnant although again not very helpful.

I had a scan at 11+6 and got quiet an good NUB shot. So far I have 100% boy guesses so we are leaning towards boy. My husband is going to find out in a month but not me.
