I went to the dr Friday and today (same thing both days). We did an transvaginal ultrasound and he couldn't see a gestational sac! I should be (around) 5 weeks 2 days today ( my LMP was February 9th. He said my uterine wall lining was thick, he found a cyst on my right ovary (left was normal) but no gestational sac! We did blood both days (still waiting on results)! Has this happened to anyone?? I also just had a baby in Nov ( I know, I know! I was on birth control so not sure why I got pg again, on top of breastfeeding). I have had over 15 positive pregnancy tests (starting last Thursday night), all getting more clear & faster by the day. Would love if anyone else could tell me their story of this happening, scared of a tubal/miscarriage.

Thanks!
Re: No gestational sac at 5 weeks?!
Why the heck has your Dr given you an ultrasound at 5 weeks? Sounds like a sure fire way to cause a heck of a lot of worry. I'd shop around if I were you and find someone who knows what they're doing. IMO they shouldn't do ultrasounds before 7 weeks unless medically necessary.
Congrats btw!

It's not uncommon at all to do a transvaginal US on a new pregnant lady to date the pregnancy. If nothing shows, to repeat.
When doing clinical's they would schedule generally week(s) apart. For some women US vaginally can cause irritation. And bleeding alone is not always a bad thing during pregnancy so not always a reason to do US.
When dating they generally use measurements from tail to rump and this is between 8-12 weeks. Not always..really depends on your dr and history etc...
