Fearing another negative

Uh, my family and friends don't know we are trying because last time it stressed me out to much being questioned every month if I were pregnant yet. I took my second round of clomid this cycle 100 mg and I'm 8dpo and fear AF will be coming. I have no where else to vent because we are keeping this a secret. I am so angry and frustrated right now I want to scream. I ovulated on day 18 but we were unable to have sex because my ovary was so swollen it hurt like hell. I'm so angry with myself that I didn't just suck it up and deal with the pain.
