5 w 5 days empty sac

Tiare

Went to the doc friday and was about 5w3days to 5w5days and there was an empty sac so they thought it could be a blighted ovum. She checked my hcg and it was 5,444. I took another blood test 13,958 so it almost tripled.

I have to go back on Oct. 3rd and docs putting me on progesterone. This is my 5th pregnancy. I lost all the others to missed MC. Have any of you had this happen and the baby was okay?
