This problem may be caused by a hormonal disorder and that`s why Murex purpurea 30x or 30c or 30k can be used. Give one daily dose for 7 days.

You can also try Pulsatilla 30x or 30c or 30k, one dose 3 times a week for 4 weeks.

Pulsatilla is a hom. remedy which primarily affects the genitals of females and is also used to be prepared for delivery.
The action on the ovary suggests its use in the treatment of ovarian under-activity leading to infertility.
