Advice / experience with Letrozole / Late Ovulation

Hi all,

I was wondering if anyone has had a similar experience to me this cycle.

I took 5mg Letrozole from CD 2-6. I started follicle tracking from CD11. First four scans showed lots of follicles but no growth. Fourth scan (CD18) my biggest follies were 14mm and 12mm. Went back in on CD21 and she didn’t even measure them, just eyeballed them and said they weren’t big enough. Although, I was and am still having tons of EWCM! She said my body is producing oestrogen but clearly not enough for a surge because there isn’t a dominant follicle.

But I’m on CD26 today and I have been using opk’s just in case (this is my one from today) because I have all the symptoms of ovulation.. EWCM, pelvic pain, increased sex drive..

I know the symptoms don’t mean I am going to ovulate but I rarely produce EWCM so the fact that I am is crazy to me! We are BDing anyway but just wondering if anyone was told they didn’t have big enough follicles who then went onto ovulate?
