No fetal pole yet?

Ka

I had US Friday and I already knew I ovulated late so I’m only about 5-5.5 weeks instead of 8 weeks. There’s a yolk sac but no fetal pole yet, my Hcg yesterday was 4800 and it was only 230 on 6/13. I had miscarriage in March and my Hcg only got up to 1100 and never doubled (which it’s doubling now) I have another us on Thursday, please send prayers and thoughts that a baby shows up! Anyone else had an ultrasound without fetal pole then it showed up?
