5dpo!! Last night my allergies were horrible, and acting up so bad, and that never happens so hoping that might be a good sign! I didn't sleep well last night which is unusual for me was up at 5:15am feeling very nauseous. Also have been having a bad headache the last couple days, have also been more tired during the day! ??
