I have a lump in my breast that didn't show up in an ultrasound but two intramammory lymph nodes were found. is that normal?

Get a medical exam: Unless you have seen a physician already, you should find one and get your breast examined(Clinical examination). If there is anything palpable with the hand/fingers, it requires follow up with a physician. Most likely it is a benign process like fibroadenoma which are benign and typically don't need any treatment intervention. But only a physician can help you make these decisions in the long run
