Lump in armpit

Jordan • Hi Everyone, I am a mom of two wonderful little boys Maximus & Krue. I am married to the love of my life.❤
So I made a post earlier but I showed my doctor this lump about 3 weeks ago and she said it was nothing. I had my baby and I am Breast feeding and now she is sending me to another doctor to see if I need a biopsy and I qm so upset. The lump is hard but it moves and it doesn't hurt. Has anyone had this?
