Hello I'm wondering if anyone got any advice to boost letrozole to work? I've fell pregnant on it once using it for the first time. To only have miscarriage at 9weeks 6days. Tryed again last month with no luck. I took tablets on day 3-7 of cycle. Unsure of ovulation days. Does anyone think it makes a difference at what time of day or night, it matters when trying to conceive. Wondering if I'm missing my ovulation window. Any help be appreciated Rachel
