Twins?

Alia
Hey ladies! This is my second pregnancy, and we conceived on our second month of Clomid. We had our 6 week ultrasound today and there was definitely one gestational sac with a yolk sac and then there was what the sonographer called "a questionable sac". Has anyone else been through this before? I go back next week to follow up. They only did an abdominal ultrasound so we weren't able to see a fetal pole or heartbeat just yet. Fingers crossed for next week!
