Weird smell? 3WPO

I am 3 weeks post op tomorrow and have noticed a weird smell on myself. It doesn’t smell BAD, I just know it’s not what I usually smell like. It’s kinda like a sweet biscuity smell, maybe almost yeasty? I thought it was just me and I asked my sister to smell close to my chest and she said “it smells like a bakery” lol

I had a complication with one of my nipples where the blood supply was compromised and I had to have my nipple cut and sutured. It is currently bandaged up but it’s turning into a massive scab so I’m wondering if that could have anything to do with it.
