Hi all, my wife is pregnant for the first time and is currently 5 weeks gone. We are concerned by her low HCG and slow incremental increase and looking for some advice. At 4 weeks, she did a scan which resulted in “pregnancy of unknown location”. She has done 3 sets of blood tests every 48 hours which has resulted in HCG counts of 77, 108 and 195. We are both really worried as up to now, we haven’t found anything conclusive. Has anyone experienced a similar situation or have any advice? Thank you.
