One breast lumpier than the other

Does anyone else have one breast that has more lumps than the other. I can feel a bunch of small rounded smooth lumps in my right breast and nothing in th left. I am 37 weeks pregnant. I had a breast ultrasound and they saw a few lymph nodes in the armpit and a bengin breast lump.

Not sure if this the lumps are just lobules/ milk ducts. Anyone else have this?
