Had a transvaginal ultrasound done, don’t see fetal pole, is it normal?

I’m a 21 y/o female and I recently had a transvaginal ultrasound done and was told that I am 5 weeks and 2 days. Since I am so early the only thing that I would be able to see is the Gestational Sac. It says “GS” where the sac is supposed to be but it’s difficult to make out and I don’t see any fetal pole and they told me it was too early to have a fetal pole. Is this normal at 5 weeks? I had a miscarriage in July 2016. They told me it was a blighted ovum.
