Hi, I have PCOD and my periods are very irregular, in this cycle I went for a follicle scan my RO follicle size was 15.6*9.7 on the 19th day and my endometrium was 6.4 and today is my 21st day and the scan is saying my RO is 12.8*9.6 and my endometrium is 6.5 and my POD is still clear , there is no liquid seen, does this mean I have ovulated or does it mean the follicle has regressed. do I have any chances of getting pregnant in this cycle?
