Hoping someone could help.

I am 4dpo today and i am having some stretchy, pully type pains in my lower left side of my uterus. These started yesterday and i notice them most when i sit down or stand up.

Also this morning i felt like i wanted to vomit (sorry if tmi) after b/fast and lunch.

Has anyone else had these cramps and were pg? I know it's supposed to be too early for symptoms but i have never felt these before. It's also my first cycle post lap so do you think that has something to do with it?

TIA
