Found Condom in our laundry 😞 UPDATE

Hey guys I need your opinions. My husband and I have a 6 month old together and anytime we have sex we use no protection. Today while doing laundry I found a crumpled up condom wrapper. First of all it's not even the brand that we buy, secondly we haven't used condoms since my son was 6 weeks old and I got my birth control out in. How do I go about asking him about it?

Update; I asked him straight up as soon as he got home and he said it wasn't his. He swears my brother shoved it in his pocket and that he thought it was a candy wrapper (my brother does this all the time). I messaged him and he said he did put it there as a joke. I know my brother didn't do it to start anything between my husband and I but it's what happened. I found it crumpled up into a ball in our jeans load, the only ones who live in the house. My husband is hurt because I didn't believe him though 😔
