Question

Can letrozole change my cycle pattern?

In previous cycles, I would ovulate around day 17 or 18 and my luteal phase was almost always 12 days. I've been taking letrozole the past two months though and my O happened on day 16 last month with a 14 day luteal and this month I got O on day 15.

Is this normal? Anyone else experienced a change in luteal phase after being pretty regular?

Letrozole is also known as Femara. It acts a lot like Clomid and helps to induce ovulation. Many women take it CD3-7 to bring about Ovulation around CD13-14. So what you're experiencing is what it's supposed to do.
