Chemical pregnancy

If anyone has any input. I had a chemical pregnancy about 3 weeks Ago I was only about 3/4 weeks along. I'm now having the same symptoms I had in July when I thought I was pregnant and I was right. My hcg was back to normal which is is we started trying right away so I know it's not my hormones. I see my dr tomorow and had my hcg checked again yesterday (didn't get the results back yet) I'm hoping my dr can give me some answers because I would really hope I am pregnant again. I keep reading success stories that it is possible to become pregnant right after a chemical pregnancy. Any success stories or input?
