TTC since January

Cortney • I`ll be 25 in just a few months. Graduated college now ready for a family. TTC SINCE JANUARY
I know many people have been trying way longer, but it's depressing.  My poor husband knows and can see how depressed I get when we get negatives.  He is so supportive which I definitely need.  But is there anything to do to help.  I take maca now I've read guaifenesin will help cm?  Anyone have experience with this?!
