Baby hidden ...

Ok so today I had my 1st appointment. I’m 8wks 4days along. They couldn’t find a heartbeat so an ultrasound was done. My doctor said “oh that’s why I couldn’t find a heartbeat, it’s hiding behind your (pelvic) bone. That’s where they start at but.” AND SHE ENDED AT BUT!!! This is my 2nd child but I’m still scared at what this means. I asked her what she meant and she said nothing it’s ok. But for some reason I can’t help but think somethings wrong ... has this happened to anyone before??? I’m seriously freaking out ... pic of my hiding jelly bean!
