Just wondering if anyone could help me with my cycle. Third cycle using OPKS and identified I don't ovulate until late. Positive opk day 16 for past three cycles of around 25-27 days. Trying for number one for 3 years and I've had two miscarriages. Wonder if I have a short luteal phase? How would this be identified but the doctors as All bloods ok. Am waiting for an HSG but on hold in current climate.
