Hi, Delays in conception can be caused by a variety of factors, including hormonal imbalances, ovulation problems, sperm quality, and other medical conditions. In your case, the thyroid issue could have been a contributing factor, but it is good to hear that your thyroid levels are now normal. It is a good idea to undergo a follicular study to assess your ovulation and identify the best time for conception. Other tests that you and your husband may need to undergo include semen analysis to check the quality and quantity of sperm, a hysterosalpingogram to check for any blockages in your fallopian tubes, and blood tests to check for any underlying medical conditions that could affect fertility. In addition to these tests, it is also important to maintain a healthy lifestyle, regular exercise, a balanced diet, and keep away from smoking and excessive alcohol consumption. Make sure to continue taking folic acid supplements as recommended by your doctor. If you have been trying to conceive for more than a year without success, it may be a good idea to consult with a fertility specialist to explore additional treatment options. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
