Worried..

First ultrasound today showed a gestational sac and yolk sac measuring 5 weeks 5 days no fetal pole ….. based on my period I should be 6 weeks 1 day ….. I’ve had 4 early losses and a missed miscarriage at 8 weeks but baby stopped at 6.1 … anyone have any positive outcomes that started like this …. I’m going to make myself crazy nuts till next Friday… my BHCG was followed for 3 tests and numbers were doubling right on every 48 hours…. Doctor seems hopeful but with my history I’m not …
