Suspected miscarriage

Hi

Before I start I dont want to offend anyone or appear insensitive.

My sil was recently in a bump in the car, no whiplash and not much damage to the car but the next day she started bleeding and this went on for a couple of weeks. She went to the drs and has had an internal and a scan and then the bleeding stopped. She has seen on her notes that they have written suspected micarriage but they have never said this to her. She said she is feeling all over the show and doesnt know if she is grieving for a baby that she didnt know that she was having. I didnt think you could have a miscarriage without being in pain but I know you can have a mmc. Is that correct as she has said that she has had no pain at all but had lost a lot of blood. I dont want to say this to her if its not right, I dont know how to talk about it to her, but I am thinking that if they have not actually told her that she has had a miscarriage, she hasnt had any pain and not had any medical interventin (d+c etc) then she probally hasnt had one. Maybe I should tell her to go backl to the drs and ask them directly? Sorry again but any advice would be appreciated. Jo xx
