SL - i had two early scans - at 5.5 and 8.5 weeks - both internal as it was the only way to get a good image. didn't see bub clearly on external scan until 12w-ish

it's not unusual to not feel pg - everyone is different in how they respond to the hormones - some of us get horrific nausea, some get horrible up-chucking - and the lucky ones get nothing major!
