Lumps under armpit

Hwayen

I've emailed my doctor and waiting for a response. Freaking out a bit. I noticed two lumps under my right armpit where the lymph nodes are. These are hard and don't move not hurt. I've been breastfeeding and am 6 days pp. Anyone else experiencing swollen lymph nodes? I noticed them when I was 6 months pregnant but they are now larger

I have a family history of breast cancer, hence the freak out.
