So My boyfriend and i had unprotected sex on early on of my fertile days and my ovulation day . I am now 5 dpo and starting at 3dpo I starting noticing increased amounts of cervical mucus- creamy, thick and white. also feeling slight abdominal cramps ,little dizzy, restlessness but can't sleep.lower Backaches also. The cervical mucus is way out of the norm for me could this be a sign of pregnancy??
