Welcome to health care magic forum,
is very common today, but it has stopped recently, some homoeopathic t/t can help u (but there should not be any serious pathological cause).
U have not mentioned weather u dont have any isssues or having it. I will suggest u that unless u have primary infertility
(No issues at all) its better not to conceive at this age because the ideal age for pregnancy
has already gone at your age there are more chances of less healthy baby as well as complications during delivery also.
But in case u want it please go to gynecologist she will rule out the cause, give u treatment and if not possible by simple means then u can take the help of IVF technique.
