I do monthly checks and a day or two ago felt a pea sized rubbery lump just above my nipple on my left breast. I feel one or two similar in my right breast just not in the same spot. My breast have gotten much larger and harder during this pregnancy but the odd thing is that when I was pregnant with my daughter I had the same lump in the same spot on my left breast. Can this be pregnancy related? It went away during postpartum. I will be asking my doctor but my appointment isn’t for 4 more weeks.
