Hi, We are trying to conceive . I have regular 30 days cycle and I don't have pcod or thyroid issues. My lmp was 20th September and my gunac asked to go for follicular study were 10th day I had one follicle on my left ovary with size 9 and and 12 th day size was 10×9 ans 12×10 . My gynac told me , even though I have regular 30 days cycle and pms Im not ovulating each month and she asked me to take ovares tablet. My question is in 30 day cycle , in which day I get ovulate is it 16th day or is there a chance to get ovulate on day 21 as well. Bcz my gynac concluded that I am not ovulating as per the study shown on day 16. But I do get all the symptoms of PMS. Kindly help me with this. Thanks.
