Rising HCG but no fetal pole!?

Daniella

LMP: 3/16/18

4/17 hcg- 82

4/19 hcg- 220

4/27 hcg- 5300

But no fetal pole on US on 4/27... I’m so nervous... US tech said sac looks closer to 4 weeks but I’m supposed to be 6???

Should I just take the meds to miscarry or let it keep going? ER doc said it’s better to end it early.... I’m so sad...
