Irregular shaped sac pls help!

[airis]

I went to my obgyn appt last week and I was told my gestational sac had an irregular shape and she said if this problem continues baby wont survive. Can anyone tell me if this happened to you before?? I already have 1 son and he's 7. For almost 7 yrs me and my husband tried to have a baby and I actually gave up hope but then i was pregnant and it was a miracle but now I feel like losing hope again. Can anyone tell me their experience in this kind of situation?
BTW, I'm 6wks pregnany and baby didnt have heartbeat but doctor said baby grew from the last ultrasound I had.

I had an irregular shaped sac the 1st time and now have a 1 1/2 yr old.  I now have it again w/ this baby (7wks along) and my doc is concerned.  When they mentioned it I thought 4 sure I'd had it before.  I compared my son's old u/s w/ this one and it looks very similar.  I found out on this site that it could look that way from having a tilted uterus and doing the u/s trans vaginally.  Does this apply to you?  I a,m still hoping for the best w/ this pregnancy.  I also just had a bleed that was attributed to a subchorionic hemmorage (spotted last week, but we weren't warned ahead of time).  I was scared to death.
Good luck to you.

typo** pregnancy not pregnant

my OBGYN said that she had patients that had irregular gestational sacs and became normal but when I tried to search it online I never heard anyone that had successful pregnant with an irregular sac or anyone that had irregular gestational sac became normal.

At my first pregnancy I had that experience. The irregular shaped sack caused by subchorionic haematoma. Also there wese no heart beat till the 8 weeks. It was a missed abortion and ended with D&C. But if the doc told you that the baby grew from the last us you should wait and dont hurry with your decisions. Maybe there are chances for your baby.
