Ultrasound

I just found out I’m pregnant(5-6 weeks) I had some light bleeding over the weekend. It was dark brown by the 2nd day it was bright red. I have very mild cramping. I never had any of this with my first so I called my nurse. They had me go to ER. I got an ultrasound and the ER dr said there were 2 sacs but one looked empty. They said the 1st one looks 5-6 weeks along. So she said I could be miscarrying the 2nd baby or it could just be too early to see the 2nd baby.

I’m really struggling with not having many answers. I’m wondering if anyone else has been in this position....looking for ANY experience with this good or bad. TIA.
