5 weeks is pretty early to see anything in the sac. So not to worry, that is normal. You should be able to see the baby in the next couple weeks. It's safe to fly. I flew when I was 4 weeks. Just don't stress about it ;) you will see your baby soon.
Since he has seen a sac, (obviously in your uterus or he would say for sure the pregnancy was ectopic) I wonder why he thinks the baby may be growing outside your uterus?
No clue, he thinks we should be able to visually confirm the embryo inside the sac by now with where my blood hormone level is at (2729). But according to him embryo could still be implanted somewhere else even though the sac is where it should be. He's definitely got me in a panic about all this that's for sure!!
My doctor seen my baby in the sac at 5 weeks but from what I have read it is not uncommon to not see anything that early so try to not stress on it I know easier said than done but stress is not good for the baby good luck mama
It can be common. I had the same case with this pregnancy. We were able to see an empty sac at 5 &6 weeks. It was until 7 week that we saw my baby's heart. If the dr is concerned about flying I would follow his directions.
i had an obliumn pregancy where the sac grew and grew and no baby inside..we did miscarry. my levels we also good but my thyroid was going from high to low levels.....they also told me it might be to small to detect or im not as far as i thought...but i started to bleed that day. good luck and i hope all worka out listen to the doctors....and stay positive! !!
