Hi ladies! 1st cycle using Letrozole 2.5 mg CDs 5-9. Pretty certain OV was on CD 16. I use OPKs and had some specific ovulation pains. Also had CD 21 labs that showed progesterone at 17ng/ml and OB says I likely ovulated. Currently 13 dpo and my Luteal Phase is never this long. Pregnancy tests are all negative so far. Only tested bc I would normally expect CD 1 to have happened a day or 2 ago. Cramps and tender breasts for a good bit of the past 2weeks. No spotting or anything when I wipe to indicate that period is going to start. Has anyone experienced a delayed period with Letrozole?
