False miscarriage?

Tina
Has anyone had bleeding and went in and had been told they miscarried but it was just too early to tell and you ended up being pregnant still? Last week, I went to the ER for bleeding and was told I was miscarrying. The bleeding stopped. A few days goes by and im cramping, more wet down there than usual, itchy nipples, twinge pains on my right side. It's not ovulation time yet. I took another pregnancy test yesterday and it was faint positive. I know after a miscarriage, it takes longer for hcg to get out of your system but I was only 4 weeks. Just wanting to know if anyone had any success stories from something like this happening?
