Today I had my first U/S

Hope
I went in to have my first ultrasound and they didn't see a heartbeat ..... I'm 6 weeks I haven't got to talk to my doctors office yet to see the complete results ... I have a friend who works there who shared my results and told me not to stress to much because it may be to early to see it and maybe I'm not quite 6 weeks yet .... I can't help but think of the worst . I had a MC in March not looking forward to another
