In general, the workup for infertility is completed after one year of trying for pregnancy without success. However, there are many reasons that someone can be having trouble getting pregnant, some of which can be explained by checking certain hormones. Irregular menstrual cycles, including long stretches of time between cycles, as well as, too frequent of menstrual cycles, should be investigated as soon as they’re recognized in someone trying to conceive. Additionally, other hormone disorders like abnormalities in prolactin or thyroid hormones can affect fertility and are important to be evaluated.
We encourage you to contact your OB/GYN to discuss your situation if you have specific questions or concerns.
