I am also concerned i always had unprotected sex with my partner and i never got pregnant. please help me.


It is likely that you are not ovulating regularly. Every month the lining of the uterus prepares for pregnancy. After ovulation, the lining remains thick for two weeks waiting for pregnancy. If pregnancy doesn't happen, the lining is sent a signal to shed. If you don't ovulate, then the lining doesn't get this signal and may only shed irregularly. There are many reasons the ovary fails to ovulate. Thyroid disorders, obesity, stress, and other conditions need to be evaluated. Typically, once any reversible cause is ruled out, treatment is based on desired outcomes. If pregnancy is desired, medication can be used to induce ovulation. If not, hormonal methods to make sure the lining is shed every month is important to prevent overgrowth, heavy or unpredictable bleeding.
