I just completed my first round on Letrozole 7.5 mg on CD 3-7. Today is CD 29. I didn't temp this cycle and now I wish I had. I really think that I O'd on/or around CD 14/15. I had major cramping on both sides with a pulling sensation at my belly button. I have never experienced the pulling before so I'm thinking it's O. I have taken 2 HPT and both have been negative.

AF feels like she is coming for the last week but she hasn't showed up yet. Could it still be to early to test positive? Have any of you had experiences with Letrozole or what I have described before. My DH and I have been TTC for 4 years now. We have tried Clomid and Soy with no luck. The Letrozole is our last effort before we have to move on to something else. We are kinda limited due to finances and insurance not covering treatments. Thanks for you help.
