Less physical activity and increased caloric intake won’t provoke ovulation! Ideally, you should have consulted with a gynecologist 5 years ago when you first noticed that you don’t have periods. Women who use birth control pills should experience monthly “periods”, although itself ovulation is blocked. Provera is a hormonal contraceptive. It is believed that after coming off Provera, ovulation can be established spontaneously. The theory is that the hormones somehow wake up the axis hypothalamus-pituitary gland-ovaries. If this doesn’t help, ovulation stimulators can be used (clomiphene). Lack of ovulation can be due to an ovarian, pituitary gland or hypothalamus disorder. You can consult a gynecological endocrinologist to follow up and request necessary diagnostic tests. Hormonal analyses (estrogen, progesterone, FSH, LH, prolactin, thyroxin…) will be probably requested.
