So cycle days 3-9 I was taking 5mg of letrozole. Had 3 big follicles got my trigger shot cycle day 12. Ovulated cycle day 13. It is now cycle day 27 I've had PMS symptoms since cycle day 24 but no AF. Very very light cramping below stomach nothing painful. Comes and goes, uncomfortable. Took a progesterone test March 10. Levels were 35. My cycles are usually 24 or 25 days. Took test yesterday but BFN. Anyone else been through this?
