Just need to talk

I'm feeling anxious because I started my 1st round of Clomid July 16th. I am afraid of how I'll feel if it doesn't work. We've been ttc for 18 months and I am just feeling hopeless. I want to see a positive pregnancy test, I want to experience pregnancy and be a mother, I want to see my husband be a father. I don't want to get my hopes up on this first try with Clomid but its really hard not to. Anyone else take Clomid this month and in the tww. I had a positive clearblue opk Friday but not since. So, is it safe to say I'm only 3 dpo?

Thanks for listening, just feeling emotional.
