SORE BOOBS!

So I'm on CD 12 and I'm 3 weeks away from my period. My boobs are sooooo tender, and there is no reason for this! lol My boobs never get sore this early before my period so now there is a little crazy voice in my head saying, "Girrrrl, you might be pregnant." 🙈 I had my period but it was super short and stopped abruptly. Tell me I'm crazy before I go drop some cash on these tests before I need to! Lmao!
