Sharp stabbing cramps 2 dpo

Maria
I'm only 2 dpo but we BD 4 times during my fertile window. Got my clear blue smiley face on Sunday. We bd last Thursday, sat, sun and Monday. Now I'm feeling a sharp stabbing pain to the left lower abdomen... Almost like a needle is being pushed thru my belly button. Isn't it too soon for symptoms or are others getting symptoms already?
