TCC -13dpo

[Fevo]

Hi all I am hoping someone else has experienced this I got a faint positive 12dpo then had some light spotting that night, today I am 13dpo and I got a darker line but still faint and more spotting. I had bloods done and they want me to come back on Monday and Wednesday, but I am paranoid I am loosing the baby. I had a miscarriage at the start of April but that was 19dpo. Help please
