Vitamins?

Draven
Hey ladies! My husband and I are having a bit of a hard time conceiving. We unfortunately had a miscarriage and October and no luck since then. We found out I have blood clots...not surprising considering I smoked and was on birth control since I was 13. (I know. Bad. Bad. Bad. Oh, to be an invincible adolescent) Well, I quit smoking as soon as we decided to start trying, and waited three months to TTC. It's now been six months, nearing seven, whoo hoo! Anyways, I was wondering if any of you lovely ladies know of any good herbal remedies to try aside from taking a prenatal. My prenatal does have magnesium and fish oil, for reference. Our puppy, Osiris, says "pleaseeee" :)
