Hello dear I understand your concern There is chance of the pregnancy but it is decreased compared to those who have both ovary. Ovulation occur for the alternated ovary. So you can become pregnant. I would suggest to consult the gyneccologist and undergo reproductive hormone analysis, USG scan and ovarian follicle study for better management. Drugs like progesterone pill in second half of period, metformin and clomiphene citrate, folic acid will help to become pregnant. Avoid stress, take healthy diet, drink plenty of water and do regular exercise and reduce 10-12% weight if you are obese. Hope this may help you Contact further if follow up needed Best regards Dr. Sagar
