Guaifenesin and fertility bracelets

Since joining the glow community I've read about guaifenesin (mucinex, robitussin) which can help u conceive and also fertility bracelets, I've never heard of using cough medicine to help u conceive before and can the bracelets really work?? I've been ttc for years and want to try everything possible to help me, I'm already charting bbt and ovulation sticks plus taking pregnacare xx
