What the heck

Well everybody, miscarried a month ago and everything was cleaned out of uterus. Got a faint positive yesterday and blood test said levels were at 22. So a week. This time last week I had light pink spotting and brown the next 2 when I wiped. Then nothing. So it’s def possible I am in fact pregnant. Also possible I could have lingering HCG left over. They never tested my levels after I was cleaned out so who knows!!! I go tomorrow morning to check again. THOUGHTS? If not, this is draining!!!
