Hello everyone,

I have a confusion about the gestational sack and when is the earliest time it can be seen on the external ultrasound?

Every reference I read online says that at 4-5 weeks pregnancy, gestational sack can be seen from an internal/vaginal ultrasound. So when I visited my doctor in my 4w, she only checked me externally (which is fine because vaginal one scares me somehow but anything for the baby), and there was nothing. One very small dot she told me it could be the possibility but nothing to be sure of yet. She just told me my uterus lining is thick so it’s a sign of a pregnancy.

But is it normal for the gestational sack not to be seen? Anyone had it before? Cause the online comments are too scary as it directly talks about ectopic pregnancy. Also my beta hcg level is 1608, and something should be seen on over 1600 I think. Never knew stepping into motherhood is that worrisome even in the first week
