complications.

Elijsbeth • Zwanger van ons 1st kindje
A several days ago I experienced bleeding and we rushed to the hospital thinking I lost the baby and the doctor found the heart beat and informed me that I have a double sac (I don't know how to say this in English) basically there was twins but one of them didn't develop so I just have an empty little sac to the side anyways that's not the point. 
I had bleeding which is not uncommon but not common and it increases miscarrying risk. 
As well as that I am a small figure girl and as well as the doctor explained some things to me that basically I have risks of losing my baby. 
I'm only 9 weeks so I'm still very early but I've been adviced (I don't know if this is how to spell that word) to not do basically anything. 
Including sex and I'm slowly becoming drained. Not because of the pregnancy but I'm so worried and I can't do anything. I don't know what to do with my time or what is safe and what's not. 
 
Has anyone else had this happen? Or felt this like?
