I missed my period and kept getting negative teats. I got a positive test on Wednesday and another on Thursday. Had an hcg blood draw Thursday that was 43. Today I took an at home test I got off Amazon and it was negative. The reviews were mixed on it so I'm not sure if it's a false negative or not. I'm scheduled for a repeat blood draw on Monday. Thinking this is a chemical because my levels should be higher being that I'm this far past missed period right? So confused
