Query: Unbelievable!

I have been through 3 cycles of IVF with no success. I have never gotten a period without being on some type of hormone, whether it be birth control, provera, or injectable fertility drugs. My infertility diagnosis was anovulatory, which means I do not ovulate on my own. After the 3 failed rounds of IVF, I decided to give my body a break. I did not get a period for several months, and then decided to try this Fertility Blend. I have been taking it for 4 months now, and have gotten 2 periods since being on it! To me, that is unbelievable! I am still hoping for a miracle-to get pregnant-but right now, getting a period without being on fertility drugs says enough about this product!
