Miscarriage

So 6 months ago I had a miscarriage at 11 weeks and 4 days the baby stopped growing at 9 weeks and 3 days. I found out I was 3 weeks pregnant a week ago and a few days ago started bleeding, then started bleeding even more the next day. I took another test and it came back no pregnant so assuming I’ve miscarriaged again. I have to go hospital to have hormone levels checked etc to make sure I’m not pregnant. Has anyone else been through the same situation as me or any advice?
