I am about 5 days late and experiencing breast tenderness but it is mainly on the side of both breasts closest to my arms. I have been pregnant before but miscarried and the tenderness last time was my entire breasts and they felt very heavy and painful. This is the same feeling but again, mainly on the sides this time and not so much my entire breasts. I tested the other day and did see a very light line on the test so I am waiting a few days to retest but I wanted to see if anyone else has experience pain on the sides?? Thank you!
