Hi,
I'm really sorry to hear about what happened. I've never had a chemical pregnancy or Chlamydia so I really don't know much about either...but as for wanting to try again and not having a normal pregnancy, I would talk to your doc about it to see what he/she thinks. I'm sure though that you will one day be blessed with a beautiful baby boy or girl and evertying will go great :) Some one I know at work had a both a m/c and Chlamydia and she has a baby boy thats almost 2 yr old now..and another on the way.
She wasn't treated for the Chlamydia until after her chemical pregnancy ended.
After my m/c I had to have a hystorectomy ... Time line was something like m/c in December 2007, hytso end of May begining of June 2008. I'm so not over the lose of my babies and so not over the whole hysto thing... So I try to stay positive in thinking that other women who still have the chance to get pregnant even though they've lst a baby, will one day have a wonderful pregnancy resulting in a baby :)
Could just be lying to myself but I like to think that way. It doesn't help me much but sometimes its easier to think that way.
Good luck. Take care. And try to keep your hopes up :)
