Stinky boyfriend

So im 5 weeks and 3 days and my sense of smell has heightened tremendously. When my boyfriend came over today he was really sour and with the heightened smell these days it's just awful and makes my stomach turn, it's so strong. He isn't always like this just when he gets off work so him being funky today is weird. I don't think he understands everything that's happening in my body right now. I told him he stinks but he did nothing about it and I feel bad because I feel disgusted. I guess what I'm asking is how can I get him to understand everything that's going on and how things aren't normal rn and wont be for the next eight months?
