5Weeks No Fetal pole

nikki • Wife💍Mom of 4💙💙💜💜

Okay so last night I went to the ER for abdominal pain and they did an US and said that there is a yolk sac but no fetal pole, I’m also measuring 5W2D. They sent me home as a threatened miscarriage, HCG was 5,678. Should I be worried? Anyone else have this happen and still be fine.

P.S. pain is from Cyst on Left Ovary
