Miscarriage, first time.

Lauren
So I found out I was pregnant 29th July, then a week later on 5th August, I started bleeding, went straight to a&e, they couldn't scan me as was the weekend, and then had to wait til Wednesday 10th August, where I had both external and internal scan, which confirmed my uterus was clear, and ovaries healthy etc. On the 6th August I was in a lot of pain, terrible cramps, and passed a big clot, the pain started to subside a little, but would then come and go for days as did the bleeding. I was told to do another pregnancy test two weeks after the scan; I did a test yesterday, and it was so so strong and clear! Clearer than when I took a pregnancy test the night before I started to miscarry. Why almost 3 weeks on is a pregnancy test showing so strong?! Surely the hcg levels have not risen since miscarrying? I have heard different things but wondered if anyone else has had the same thing happen? I've spoken to the EPU and they have booked me in for a scan in a weeks time, providing pregnancy tests remain positive! So confused! As the lady on the phone was almost hinting it could be possible I'm pregnant again?! The pics show the faint one which was night before I miscarried, and the bottom one was the one I took yesterday.
