I just had in vitro fertilization done a week and a half ago. They implanted two embryos. I am due to have a blood test done tomorrow. I had implantation cramps about 5 days ago and have gotten several positives on HPT's in the past couple of days. Today, after going to the bthrm, there was brown blood on the TP. This makes me nervous. I was thinking that maybe it's just leftover from implantation since it's brown or maybe it's from the second embryo implanting now. I worry that it's something worse though. Does anyone know what could be going on or if I could be right about one of my theories. I'm freaking out. Thanks for your help.
