So confused

Angela

I had my second vaginal ultrasound today and was told that my gestational sac is bigger than the fetus. The ultrasound lady didn’t say to much, she did find a yolk sac & fetal pole but was even unsure herself why the gs was bigger. Does anyone know what this means or if it has happened to anyone. I’m so confused all I am trying to do is get a due date because I don’t know when my lmp was and everytime I leave the sonographer I’m more confused than ever. I see the dr tomorrow for results but all this is doing my head in. I’ve had 3 previous miscarriages in the past 2 years so I can’t enjoy or get excited about any pregnancy at the moment 😔
