still smelly

I was prescribed some cephalexin for bacterial infection i’m 6 weeks exactly today and the smell is still there and I only have two days left of the medicine. I thought the smell it would have gone away by now 🥴 or is this just bc I have a strong smell from the pregnancy? no matter how much I wash up the discharge comes back and makes my underwear smell and i’ve been using non scented detergent on underwear so I know it’s not that..
