I am due for my period any day now and as per usual, my boobs are mega sore and have swelled up but this month things seem to be a bit different as only one boob is swollen. The right one is noticeably bigger than the left. I touch them and play with them but ever so gently as they are very tender. I lightly squeeze them together, jiggle them, bounce them and play with my nipples. It feels good because they are so sensitive right now but it won't be long before they go back to normal and even back out again.
