Scary ultrasound


Any advice? Last week at my first ultrasound they said I had a gestational sac but nothing else, dating me a week earlier than we thought. Went back today (7 days later) and they said I have 1 gestational sac, 2 yolk sacs and 1 fetal pole...they did labs and want to compare my hcg levels in 48 hours. Told me it could be a molar pregnancy that we’d have to terminate or that it could be twins, but the PA wasn’t very promising and said she didn’t know...has anyone experienced anything like this?
