Help!

Okay I'm so so very clucky and it might just be me being silly..
But yesterday and the day before I was having really different cramp like pain a sharp pain also like around my uterus and ovaries, that would have been two/three days after my fertile window is that too early for pregnancy symptoms? I feel like my body knows how badly I want this an she's playing tricks on me LOL 
Please and thank you any advice is good
