It is going to be a long 4 days.. My boobs have been aching for the past few days. Normally before AF they are sore but it's usually the side like under my arm pit. This time it's my whole boob and my nipples are very sensitive. I remember when I was pregnant with my second when I showered I had to cover my breasts because the water hitting my nips hurt. I've noticed lately while showering it's the same thing happening and haven't changed anything as far as pressure. Wish I knew if it was AF approaching or not.. Sorry so long, jus needed to get that out there. I'm wanting to surprise  my hubby if I am pregnant so don't want to tell him anything is going on.
