What to do and where to go if nothing comes out of trying to have a child?

In case of problems with the menstrual cycle, the gynecologist is the right specialist. In the case of severe pain, you should not delay the consultation. Unfortunately, I do not know what you have been doing for two years. If there is no menstrual bleeding, then it is difficult to consider it a correct situation. However, when it comes to the absence of a child, the commonly used definition describes infertility as the inability to obtain pregnancy for a period of 12 months, despite regular sexual intercourse (2-4 times a week), without the use of contraceptive methods. Indeed, some couples try longer and succeed, but the aforementioned period of a year without pregnancy is a time after which it would be necessary to deal with solid diagnostics, allowing to assess whether there are any disease or anatomical causes for which conception does not occur. If you care about getting pregnant, it is worth looking for gynecologists in infertility treatment clinics, which deal in a special way with diagnostics and treatment in case of problems with obtaining pregnancy.
