Ugh, PMS! It’s just not fair. My breasts always hurt when I’m about to get my period, along with my lower back. I also get crazy massive cravings for sugary or salty things. Oh and don’t forget the cramps. In short, leading up to your period, your body starts producing more hormones and that is what causes all the aches and pains. The good news is that soon after you get your period, all of that will go away. If the pain gets to be a little too much, try some ibuprofen.
