Secret fertility

Last month I started taking Clomid. My husband and I had a misunderstanding and he thought it was to fix my PCOS and not to have a baby, so I had to stop taking it. WE aren't ready but I am. I'm afraid I'll run out of time and I've wanted a baby for so long and after a miscarriage, I just can't shake the feeling that I am supposed to have a baby. I am also very impatient. SO...... I renewed my script for Clomid and I am strongly thinking about taking it without telling my husband. How bad of a person does that make me? I know I'm selfish hut when we had the miscarriage it hurt him just as much as it hurt me. And I have never seen him so happy as when I was pregnant before. He was so excited to have a baby. He just says we aren't financially ready, but if we wait until we are financially ready, we will never be ready! What do I do?
