Periods due on 30th. Tested today afternoon around 3- 3:30pm. Pee is not diluted. Not sure why dpo I am but I think it’s 12 dpo. Experiencing few symptoms like lower back pain, cramps, pinching in middle. Sore breast. Am I overthinking or there is a line? Is it too early to say “yes”? Or very faint line for 12 dpo? Please give me your opinion.
