Any Women TTC Take Cassava?

Girl Mom. 🎀 • Mama bear of two!
Hi! I just read quite a few articles on the cassava root pills. They apparently help boost your chances of fertility. I just got done ordering a bottle, but I am a little skeptical. We've been TTC for 5 months now and we had a miscarriage 8 months ago. Cassava root apparently also increases your chances of twins, and there are many sets of twins in my family so I honestly hope that's true. I'd love to have twins. Anyway! I'm just wondering if any other women have taken these cassava root pills, and if so how did it go? Did you get pregnant? Any side effects? Are they a waste of money? Any help is appreciated! :)
