My friend who just got her BFP last week registered a very gigh HCG reading today. She had 2 embies put in and her initial reading was 498 at 4 weeks 1 day. Today her second reading was 6130 at 5 weeks. Could it be a singleton or or a multiple pg? She asked me to come in here and ask the question. Has anyone had a high reading like this and what was the outcome?
