Can anyone explain what kind of breast pain you feel as an early pregnancy symptom? I am pretty sure I am pregnant and I have started having some pain in my breasts the last couple of days but I can't tell if it muscle pain or not. I teach special ed so I do a lot of lifting during the day. If anyone can tell me whether the pain is in the whole breast, just the nipple area, or what and does it feel like muscle pain? Thanks in advance for your help:)
