I had irregular periods, along with being tested for PCOS I also had my thyroid checked. I was determined to be hypothyroid. With the medication for the thyroid alone, my periods came back pretty regularly. As far as it helping you with TTC, I don't know. I haven't been on it that long, and I haven't been really trying that hard. I did see a gyno about taking fertility pills, and with me being obese, he said I would have to loose a great deal of weight before he would give me any. Depending on how obese you are you might have to work with getting your weight down before a doctor might aid you in getting pregnant. And trust me when you have hypothyroid and PCOS loosing weight is one of the toughtest things to do. I hope for your sake it is not PCOS. Good Luck!!
