My husband is nervous beginning his medication

Rainbows & Unicorns

After a few years it's my husband's turn taking clomid and hcg medication. He's nervous. I'm trying to be understanding and patient, but it's been over a week and he still hasn't started the 3 month long process of medication. He says he's waiting to hear about work to make sure he isn't going to be relocating soon and that's why, but in the same sentence states he never knows for sure until the day of if he'll be leaving.

I'm trying to be empathetic and patient, but I just see time passing by where he could be making this improvement to his hormones and semen.

Are there any words of wisdom y'all have for him that I can relay?
