Hi and thank you so much for this query. I am so sorry to hear about this absent cardiac activity on the ultrasound. Every other finding indicates that the p[regnancy in increasing in size and the gestational hormone titer strongly suggest this. I will suggest that you get a repeat ultrasound iin 4weeks to control this again. if there are no signs of a cardiac ativity, then other possible causes of gestational tissue without fetal activity like molar pregnancy should be considered. Do you have exagerrted nausea and vomiting? These could be suggestive and if the titers are rising higher than expected for age, this should be strongly considered. For now, be calm and go for a folow up control. Depending on the findings, active measures can be pursued or reassurance if the cardiac activity is clearly seen I hope you find this helpful. Thank you so much for using our services and please feel free to request for more information or clarifications if need be. I wish you the best of health. Dr. Ditah, MD.
