Had my first ultrasound today, saw a gestational sac and maybe saw yolk sac and baby although lady wasn't sure, if it was the baby it measured at 5 weeks and 4 days which is exactly what I thought I was. The lady did however find a moderate amount of fluid above my sac, which was a bit worrying for me! Has anyone else had this before? I am not spotting or anything. The ultrasound hasn't reassured me much, as the lady suggested I still get my hcg levels checked:(
