Pregnancy symptoms?

It it possible to have the following symptoms after one - three weeks of possible conception ?
Bad fatigue 
Really sore to touch nipples
Slight nausea 
Slight cramps 
Cervix really high can just reach it and it's kinda hard with sticky white cm 
AF is due in four days and I do honestly feel like I am pregnant but it's too early to test so I was just curious what you ladies think ? 
(On a side note I also had sex on ovulation day 7 days ago so that makes me now 7DPO)
