Patient's question:
NoDoctor's answer:
Generally, in the early stages of pregnancy, the blood HCG level doubles every 1.5-2 days, and serum progesterone gradually increases. Around week 6, an yolk sac can be observed via ultrasound, and between weeks 6-8, a fetal pole with a heartbeat can be seen. It is recommended that you recheck your blood HCG and serum progesterone, or have a follow-up ultrasound in one week.
