Do you feel breast shrinking at week5 +? I felt it since yesterday! Weird.

5/June: HCG 5000+ Symptoms gone, except abdominal discomfort, squeeze the nipple to feel the soreness, u/s can only see sac, nothing else.
8/June: HCG 12000+ Symptoms gone, except abdominal discomfort, squeeze the nipple to feel the soreness
9/June: Symptoms gone, breast shrinking, no soreness, don't feel like eating at all

Am I OK?! Help!!
