5 weeks ultrasound what you can see??

Ay

Hi girls

I have an scan next week. I became pregnant without having my period after my miscarriage and my doctor wanted an early ultrasound. I’m so worried it be too early to detect the baby. I didn’t have period but I checked my ovulation every day and I guess I will be 5 weeks by the time I will have ultrasound. Does anyone have an early ultrasound experience???
