Not sure where to post this I'm still kind of new

My husband and I have been ttc for over a year now and we are wondering what the best medicine is to help us to get pregnant that we can try!! It's kind of depressing for many reasons and one of the biggest reasons is my 3 almost 4 year old keeps asking me to "go get" her a lil brother or sister!!!! Anything helps please no rude comments thanx in advance!!
