Navel leaking pus 🤢

Asia

Hi moms 👋🏽 I’m a First time mommy here currently 36 weeks I’m getting induced Friday which I’ll be 37 wks . I’ve been having pus leak out of my navel ( and before you ask no it’s not from a recent piercing) in the middle of my navel is a small hole leaking out the pus it leaks the most when I urinate it’s sore to the touch or when I bend over . It has a slight yellow color to it and around my navel is very warm fever like .. my doctor said she never saw anything like it when she tried to get a sample of it nothing came back because I had just cleaned it right before I made it to the office 🤦🏽‍♀️ they put me on antibiotics. But I’m just concerned on what this could be ? & if anyone has experienced this ?
