Dear fozzy380-
While it is possible that the

Miscarriage, or any surgical procedure for that matter, could cause scarring of the uterus and fallopian tubes, it is actually very unlikely and uncommon.
As a rule we start to worry about

Infertility - resources
Primary infertility if a couple have been trying for 12 months and have failed to conceive; 6-8 months if the

I would recommend that you continue to try for another 2-3 months, and if still not pregnant make an appointment to see a reproductive endocrinologist/infertility specialist. If you end up needing to see the fertility doctor, they will do tests to see if you are ovulating (which I am sure you are based on your regular periods), to check your partner's sperm count (which hopefully will be normal since he has a child, but which is not always the case), and to see if your fallopian tubes are open. With the results of this test, they will be able to recommend the best treatment.
Good luck.
