6 weeks and 1 day, no visible fetal pole

Sed
When did you guys see your baby's fetal pole? I am kinda worried. Been to the OB to get an ultrasound (to verify how far gone I am into the pregnancy) today and two weeks ago too but we're not seeing any dot. Just thickening of the uterine wall. PTs are positive. OB says there's no problem and to come back after two weeks. Guess I am too early?
