I don't get my period on time, sometimes i even skip a month. will i have trouble getting pregnant? (25 years old female)

Possibly: Irregular periods may be a sign of an underlying medical condition that may affect infertility in the long run, or may be the result of pregnancy, medications, or weight loss.Some of these conditions are more easily rectified than others, so see your doctor to be evaluated.

Depends: Irregular and missed periods happen due to irregular or missed ovulations. By definition you have mild ovulatory dysfunction, the most frequent female fertility problem (30%.) if this is the only abnormality you and your partner have, you may not even have problems conceiving. If there are other problems, depending what they are, your chances could be less good.

Maybe. Find out why: It might take longer to conceive because you're not ovulating regularly. We can find the cause: polycystic ovarian sydrome (pcos), thyroid or prolactin hormone issues, aging of the ovary (less likely at 25), or low hormone levels from exercise, eating disorders, or stress. See a reproductive endocrinologist for tests / treatment when you're ready to try, or after 6 months of trying. Best wishes.
