Bleeding but doctors unsure?

HI I am 8 weeks 4 days, I've had some red bleeding for 4 days now. I went to my Dr they did a abdominal u/s but my uterus is tilted so far back they can't see the baby clear, the gestational sac is still growing but they're unsure if the baby is alive or if I'm miscarrying..has anyone had this happen before and everything be ok?
