I didn't have the bleeding, but at an early scan (with our 2nd bub) it was too early to see anything in the sac and I know you can't always rely on the date of your last period. (I don't ovulate regularly) I have several friends who have 'O'd earlier and later than usual, resulting in 'surprise' (unplanned ) pregnancies and I think pg tests are pretty quick at picking up pregnancies pretty early now, so you could have been not as far along as you thought when you did the test.

Good news that the bleeding has stopped. All the best xoxo
