Am I Out?!!! So lost!

Did a blood test today and cane back negative at 12dpo 😭💔 My period is supposed to come on Friday the 8th. My boobs have been sore and tingly, my discharge is milky white and wet, and I just feel pregnant but this is all so discouraging! On top of everything over the last couple days my toddler almost three years old has all of a sudden become clingy! He’s never been one to snuggle even as a baby so idk what to think! Ahhhhh!!!! I’m going insane!!! 😭💔😩
