Husband thinks I'm pregnant

He says I've been more moody than usual and I'm starting to agree. I've also had a craving for Cheetos and I used to LOVE ice cream, now I don't want any part of it...I've also been getting head aches more often. And atm we don't have the money for a pregnancy test..I've also been feeling sick a lot lately....help

Update:

We got the test.. I see a faint line
