5 dpo

So, i ovulated on January 24th, we BD  the day after also. Now unless it's all in my head but I'm having super weird symptoms. I can't explain it but I just feel not myself ( anyone else this way) 
I get more nauseous at night time
I have pressure / cramps below my belly button and like out towards my sides (ovary area) 
Backaches -- bloating -- gas. 
Again I feel crazy haha 
Im due for my period February 7th and I know it's to soon to test or think anything is happening but just looking for opinions. 
Thanks in advanced ! :)
