Smell?

My husband cuddling with me on the couch today tells me that I stink 😳. Well he basically said "neither of us showered yesterday and we smell we need to shower". Long day with the kids and everything and we fell asleep and didn't shower. It happens. Rarely.. but oh well. Still though.... I said "I actually smell?!" I asked him like BO because I can't smell anything.. as I proceeded to smell my armpits lol. He said no not like actual legit BO you just smell babe it's fine I smell too who cares we just need to shower. 😂 I can't figure it out. Where is the smell coming from? Obviously I'm going to shower like right now but... it had me worried. Can other people smell me? He said he noticed it in the truck this morning taking our oldest to school. Must be my armpits. I'm sitting here thinking I can't smell it and I don't have like a vaginal bacterial infection or anything that I can tell... that wouldn't smell to the point he could smell it being next to me right?! I'm just worried LOL. WHERES THE SMELL COMING FROM 😳
