My last preg I was bleeding so went for early u/s, there was nothing on u/s, told I had a complete m/c, hcg kept increasing, was still bleeding, told must have an ectopic and went for another u/s 2 wks after initial one - voilla - there was a a baby!!!! Was too early at first u/s to see bubs as I had an irregular cycle!

Fingers crossed for you!
