Today was tough

I am currently 6wk 4 days pregnant, I’ve been bleeding throughout today and it has gotten heavier, I went to hospital this evening and they done bloods and an internal and external scan, my bloods came back at 600, I don’t know if this is normal, but I have to go back in two days to repeat bloods to check the number has doubled for the pregnancy to be viable. There was no sign of baby on either internal or external scans. Has anybody had this happen before and experienced a good outcome? Feeling hopeless 😭
