Hi and welcome to HCM!
Thanks for posting your query here.
is a bag like structure around the embryo. Its presence shows a proper implantation
of the embryo within the uterus. So an ectopic pregnancy
is ruled out. It will take time for the fetus to form-hence fetal pole
not seen. Internal os closed- this rules out any chances of abortion. All the other parameters are absolutely normal.
So stop worrying and enjoy the fatherhood.
Hope this is helpful to you.
