On the Saturday between that Thursday and Monday HcG I had a negative pregnancy test at home. Now my tests are the darkest they’ve been this pregnancy. What on earth is going on? Even my doctor is at a loss. We decided I’d come back in 2 weeks(unless I have bleeding or pain). Until my level is 1500 we can’t do an ultrasound. Just looking for some other perspectives. Vanishing twin? Ectopic without pain and/or bleeding?
