Sac no visual of baby

chris

Had an ultrasound the other day but there’s a sac but couldn’t see a baby. My hcg levels are in the 16,000s so doing a repeat ultrasound in a week. My ob asked about history of twins my mom is a twin and that could be a reason why they’re not seeing a baby. Based on my lmp I’m 6 weeks but we started trying the 12th so I could be early. It’s driving me crazy idk how far I am. I could be 4-6
