Letrozole and Trigger Shot - Am I Doing It Right?!?

I have been on 2.5 of letrozole for six months and have had two trigger shots. Month one I only had 1 follicle. Month 2 I had ten follicles.

I’m not sure how many times you are supposed to BD during that 36 hours. We did it several times, the last being at hour 34. Should we have done it past the 36 hour mark as well??

I’m just so frustrated with the lack of success.
