5 or 6 weeks pregnant? Unplanned pregnancy questions?

Muvvagoose

my pregnancy was completely unplanned. I went into planned parenthood for a new IUD and I am now pregnant! Doctor did a transvaginal ultrasound and only saw a sac measuring 1.1cm which to her is 5 weeks 1 day . She said if I was father along she’d at least see a fetal pole. Did anyone see a fetal pole or yolk sac transvaginally between 5.5-6weeks? Just a little worried because my hcg levels were in the 20000s but there was no HB or pole.
