Pelvic bleeding

Two days ago from 7 am to still now I had pain in my lower abdomen and then yesterday I started bleeding at 5am so I went to the hospital and they didn’t tell me ANYTHING besides giving me a rhogam shot. I got home and the bleeding started again but worse so I went to another hospital and was told I could be hemorrhaging and to be on pelvic rest and bed rest. So now I’m just laying down scared out of my mind and upset. I have my normal anatomy scan Friday so hopefully everything will look good and have no more bleeding

Also I’m 20 weeks pregnant
