Right breast lump

I am 20 years old and i know that it is very unlikely for breast cancer to happen in that age group. I am also 24 weeks pregnant. So i have a question. I noticed a weird hard bump on my right breast by my armpit. I have never had that lump so i started worrying but forgot about it. And now i noticed that i have another lump too on top of my right breast too. They are not visible lumps but when i touch my breast i can feel them, They dont hurt and there is no discoloration or anything. I was reading on it and it said that it might be because of my pregnancy it can be clogged milk ducts or it can be an infection. Have you experienced this especially ever during your pregnancy??
