As I understand from your question, it seem that you have 3 problems: painful and irregular periods, sterility, and an abnormal Pap-smear (precancerous cells).


The first two conditions are probably related. Irregular cycles usually occur without ovulation and can be the cause of sterility. Irregular cycles can also manifest heavy bleeding. Birth control pills can help regulate menstrual cycles but will continue to lack ovulation. In fact, birth control pills and the hormones therein stop ovulation. The point is that after coming off them, the axis hypothalamus-pituitary gland-ovaries should spontaneously re-establish ovulation and keep menstrual cycles regular. It seems that in your, case birth control pills didn’t help. You can request hormonal examinations for all hormones that impact fertility (FSH, LH, prolactin, estrogen, progesterone, testosterone, DHEA, thyroxin) and check if you are ovulating, or not. If you aren't ovulating, then you can consider requesting ovulation stimulators (clomifen).


The third condition you mention might be taken very seriously. Precancerous lesions on the cervix (dysplasions) can transform themselves into a cancer sooner or later, depending on their level of development. You might take a Pap-test twice a year . If the Pap indicates dysplasion of grade II (mild) or III (severe), you can then request a cone-biopsy (conisation). You might be also checked for HPV-infection.


You may try to get pregnant only after you treat all cervical precancerous lesions!
