Just found out im pregnant, maybe 5 weeks, and my breasts are so sore and heavy i cant even sleep on my side. Is there a reason this happens so early? curious to know whats going on inside.
Those early changes are your body prepping for feeding later, totally natural. The soreness eased for me after the first trimester. A comfy wireless bra and gentle handling made it bearable.
It is the hormones, mainly the rising estrogen and progesterone preparing the breasts for milk. My doc said increased blood flow makes them tender and heavy. It was actually one of my first clues I was pregnant.
