Cold feet about Clomid

Ttc for Over a year now and tomorrow will be the day I start clomid(5-9 shout out to my cycle buddies). I was over the moon when I first got the prescription. The thought that I could have a baby by the end of the year, lit my heart up. DH is so excited but I still can’t help that little voice in my head saying “it’s not going to work”, “you still won’t see two lines on that hpt” 😔 what if it doesn’t work? I’m trying to hold onto to, what if it does? I’m just venting... nobody really understands outside of this app..
