I didn't temp this month I mostly guessed we were planning on starting to TTC next month. From what I can figure I think I'm 8 DPO and if I am pregnant would be 3w1d. My BBs are really sore, I'm crampy and today I have been exhausted. I have a digital test but i'm worried its all in my head. I don't know if I should wait (I'm not a very patient person) or go get dollar tree tests and use my digital to confirm. Is it too early for most people? I don't know if most of these "symptoms" are in my head or actual symptoms. Let me know what you think.
