Most women consider period as their marker for everything. Whether be fertility or pregnancy sign. Period is a part of your reproductive health. Undoubtedly male infertility could be a reason for not being able to conceive but there are other reasons in women too. What exactly is your case is difficult to predict. If you’re seeing signs of ovulation, having regular period, not taking any prescription contraceptive or otherwise and having a healthy lifestyle then consult an OB about your partner’s fertility tests.
