Advice..?

So yesterday 9dpo I got a faint positive, DF found out & now he's kind of ify because last month we had a chemical pregnancy. I'm a little sad because he's doesn't want to get excited. How do I convince him that I am prego. At 10dpo my boobs are so sore & I'm cramping here & there. I'm also already nauseated.
