Three months are not a long enough period to confirm that you are experiencing sterility or not. At least one year without conception should pass to say that you and your partner are experiencing sterility.
Irregular periods could be a sign of the absence of ovulation. Vaginal discharge is not a sign of ovulation but could be sign of some vaginal infection. Infection with Human papiloma virus (HPV) can cause cervical cancer but not sterility. There are several methods to identify whether or not you are ovulating. You can follow up with your gynecologist
1. Measure the basal temperature – several hours after ovulation occurs a slight rise of the body temperature also occurs;
2. Ovulation tests – detect the increase of Luteinisating hormone (LH) in the blood and urine that happens several hours before ovulation;
3. Progesterone detection in the blood – after ovulation, the remaining follicle is transformed into a yellow body that produces progesterone;
4. Cyto-hormonal examination – presence of progesterone causes domination of intermedial epithelial cells in the Pap-smear, and
5. Ultrasound examination – a follicle that is ready for ovulation and yellow body can be seen by ultrasound.
