HELP! TTC! I FEEL DIFFERENT

Madeline • Married 10.21.17 ❤ Pregnant with our 1st ❤👶

Hi guys! So I'm 12 DPO and my stomach feels HEAVY, cant suck it in anymore, exhausted, feet aching, I'm forgetting things constantly, I feel out of my body... hot, kinda dizzy, emotional. I'm very nervous to take a pregnancy test and AF is due in 3 days. Do I wait?!?!?! Is this common?!?!
