Started spotting got scared

Bella
So I started spotting yesterday didn't think anything of it cause I heard it's normally but today was a little more so I called my doctor she order an ultrasound. Went to my first ultrasound (viginal) got excited that I would get to see the baby but the tech didn't didn't should me the baby. Got even more scared. Was told to wait cause they wanted to make sure the pictures they did get was clear. When the tech came back she told me it was to early to tell but that they do see the sac. I'm supposed to be 9 wks on Tuesday. Shouldn't they be able to see the baby by now? Has anyone else experience this?
