Nursing bras

Cori

I’m 34 weeks, FTM. I have 5 nursing bras and have been wearing them because my other bras don’t fit me. I only have problems cleaning one of them. The pads in the inserts smell after I washed them for the first time. Its such a weird smell. Not mildew. Smell is hard to explain. Not sure how to wash these or get the smell out? Anyone have the same problem or any advice on how to get the smell out?
