I'm a 35 year old mom of one. Lately my breast started out itching no stop. Now for a week the nipple is erect haRd and so sore and tender. I have mild cramps and brownish spotting to light bleeding. I didn't have these when I was pregnant with my son. I have been trying off and on but I'm not sure. Oh last few days lower back pain and a bit hungry more. Feel more sTressed. nipple area is a bit darker. On more so than the other. Is this the start of PBS which I have never had or pregnancy?
