ectopic ???!!

hi everyone I'll try and make this quick . basically almost 4 weeks ago I had a miscarriage at 6 weeks it was my 2nd one with 3 years inbetween. I thought I may be anaemic so requested a blood test for my iron levels but Dr wanted me to go for a scan because I'm still having positive pregnancy tests. I went for the scan and it showed everything had gone just a small amount of retained product in my cervix , however I've had hormone tests 48 hrs apart and my levels have gone up from 668 to 880. they've said they can't rule out pregnancy in another location. I'm having bloods and a sample of tissue taken on Sunday to get a better picture of what's going on but I'm terrified im going to have a ruptured ectopic . They don't seem to be in any rush to get me in. Has anyone had a similar situation happen to them that could tell me the outcome that they had xxx
