Do you mean to say that your sonography is still showing PCOS? It is good that you have lost weight but it is equally important to know what was your original weight. If you have lost about 10% of your original weight; it is optimal and you need not lose any more weight.
Next Steps
Are your cycles regular? If your cycles are regular; there is a high chànce of you conceiving naturally. Equally important for you to know that PCOS pts who have irregular cycles also may occasionally ovulate after losing weight. If you do not conceive spontaneously; consult a fertility specialist who may put you on Ovulation medication which has a high chance of success rate.
