Ttc after miscarriage & Soy Isoflavones

So I had a miscarriage at almost 6 weeks, which was a clomid baby, but I ran out of clomid and I won’t dare to ask my doctor to prescribe more because of my miscarriage. I did research on Soy Isoflavones many women has swear it has worked for them, so far it looks like I’m getting close to ovulation so lets hope it does work, Im 7 months pp & it had previously took us 9 years to conceive our babygirl.

Has anyone taken Soy Isoflavones after miscarriage and had a successful pregnancy?
