5dpo symptoms! Anyone else?

Kim • Momma of a princess. Pregnant with baby #2
Today I am 5 dpo. Ever since yesterday I have felt like I was coming down with a cold. I have had cramps/pressure in my lower abdomen for the past 3 days. I feel nauseous & fatigued until bed time then im wide awake. Headaches on & off. Hotflashes & Chills. Anyone else had these & ended up pregnant?
