So my DR. prescribed Letrozole 5mg for CD3-7 & Provera to jumpstart my period. I started the Provera on April 15th & my period started on April 24th. I started the Letrozole on April 26th & stopped on April 30th. On May 4th (CD11), I had what I thought was EWCM but it was a little more opaque... I also thought it would be too early for Ovulation. However, the DR stated that I should Ovulate on CD12. From CD12-13 I have been dry... I am confused as too if I already Ovulated or if it's about to begin... I have been checking my CM everyday & my BBT every day. The BBT method is a little confusing to me & I am not seeing any changes at all... Also, all of my OPKs have been negative & I have been checking them since CD5 because of my PCOS & irregular cycles. I know I shouldn't rely on apps, but all of my apps are saying that my fertile window started today (May 7th) & I should ovulate on May 12th (CD18)... Should I just keep BD & see what happens? Or what should I do? I thought I should add that I have been taking Metformin & Prenatals...
