AF due between August 18-20. Cervical position?

Jessica
I'm currently 5dpo. TTC baby # 2. I'm pretty new to tracking my cycle. With baby # 1, I didn't know half the things I do now about ovulation. Also, I am very new to checking my cp, but I thought I'd try. Yesterday it felt high, but this morning it was definitely low and hard. Does this mean that I am not pregnant?
