Hello Sana and welcome. Pregnancy is certainly possible, but it depends entirely on how you respond to the medications and the condition of your ovaries. What worries me is that you have PCOS as well as a thyroid abnormality. All we need to do is bring your menstrual cycles to a more regular state, help them last an appropriate duration (approximately 28-30 days) +/- 5 days. Once this is achieved we can initiate clomiphene citrate and if required hCG injections as well to increase the fertility status. I am hopeful, and think pregnancy should be possible. Sana, please be positive and do not hesitate to use our premium(paid) service and write to me directly, asking for me in your query. I will be able to discuss things in a more elaborate manner with you through that. Hope this helps. Best wishes.
