So what can I expect?

I'm devestated. I've had DD and both DH and I have been tested and don't have Chlamydia so it would have been from a long time ago and I wouldn't even have known. Apparently the antibodies that are created when you get the infection can kill the infection off, hence why I wouldn't have known.
So my questions are these:
If I have the laparoscopy and they find that a tube is blocked, will they remove it? (I'm guessing that they will to remove risk of ectopic PGs).
If the laparoscopy doesn't show that the tube is blocked, but that there is just some minor scar tissue, what are the risks of them trying to remove it and also what are the risks of the laparoscopy itself?
Can we continue TTC straight away (within weeks - obviously not days...) after the surgery or do we have to wait a number of months (I hope not... - time is not on my side) 
If they remove a tube and the other one is completely clear (they are assuming that one is definitely clear because we have had DD and another pregnancy two months prior to DD that was definitely in the uterus but unfortunately ended in natural MC at 5 weeks), do we still have a good chance to conceive? They told us that apparently you can still OV every month even with only one tube as the tube can move between the two functioning ovaries.
If anyone has any experience of any of this, can they please PM me or just offer some advice on this thread. Scared and upset.
