I can semi-understand what you're going through, not through actual experience, but I have a 50/50 chance of being infertile when I do try to conceive and I have a high risk of miscarriage if and when I do get pregnant. The best answer has already been said, and that is to go and see your Gynaecologist, you've been trying for some time, so it's not like you're rushing into an appointment about fertility.
