I'm 14 dpo, due to start my period today. I have been testing since about 9 dpo and NOTHING. My boobs have been super sore for a week now and a few days ago, my nipples became sensitive and sore. I have also been cramping for about 5 days, which is unusual for me. I usually cramp a day before AF or so. Plus, I have developed a sore throat which has lasted about 3 days. 😩
