I am very sorry to hear about your miscarriage; a miscarriage is extremely traumatic for both the husband and wife, and the added problem of difficulty conceiving after the miscarriage must make it more painful. Conception is not always as easy as we think it is, and sometimes it takes a long time without there being any real problem. However, if you and your husband have been trying to conceive for over three years, then there is certainly a problem. You should not lose hope however, as most fertility related problems can be solved quite easily. You will however need to consult a doctor, preferably one who specializes in infertility. There are very many possibilities, and it will take a thorough investigation and probably several tests as well in order to diagnose the problem before being able to fix it. There is no simple solution to conception problems, and each specific couple will need to take a unique approach.
One thing that it is important for you to do is understand the circumstances of the miscarriage. Miscarriages are not uncommon, and it is not always possible to identify the reasons, but if you can, you should try to find out what caused the miscarriage. Another thing that you should look into is whether the procedure that was performed to remove the placenta from the uterus could have caused any damage, or alternatively, whether there was a problem to begin with, due to which the placenta was not expelled. This problem, or the damage caused by the procedure of removing the placenta, could be related to your current difficulty in conceiving.
If such information is available, the specialist who you consult will find it easier to determine the nature of your problem. One the problem has been identified, the doctor will recommend a course of action, and in most cases, a couple is able to conceive after this.
