Is it normal to not see anything? I had a dating ultrasound (internal) on thursday as I'm not 100% sure when my last period was, but I think I'm about a week past my missed period. She couldn't see anything, not even the sac. I've had six or seven positive pg tests - the report from the radiologist said it could be either a very early pregnancy, an ectopic pregnancy or a miscarriage (I haven't had any bleeding). I've had a blood test today, but I'm quite scared this is an ectopic pregnancy.
Has anyone else not been able to see anything on internal u/s at around 5-6 weeks? Please help put my mind at ease
