Could i be?

Kylie
Ok ladies im in need of some advise. Here are my symptoms that started about a week and a half ago. I need some help on figuring out if i could be pregnant. 
Random nausea
Still get occasional very slight cramps 
Fatigue
Gas lots of gas
Frequent urination
More thirsty than usual
Hot/ cold flashes (not often)
Appitie changes
And occasional lower back and pelvic pain
My period was 2 weeks ago and it has been irregular the last few months. These symptoms first started with some very light but noticiable cramping about 2 days after my period finished. (We did the deed the day i stopped bleeding) it is too early to test but its driving me nuts. Help!
