Same here. Happened last year accompanied with bleeding. Went to A&E and can only see the gestational sac. Went thrice to 2 different hospitals. Same answer everytime. Was also prescribed the hormones pills. And my gs stayed the same at 5 weeks for 2 weeks. Was sent to fetal care centre and it was confirmed baby is gone 😭 But do not lose hope. Maybe baby is still too small to detect. Wait for another checkup. All the best mummy!
