I need some advice.

I dont know if I'm pregnent and I have a test but I dont wanna use it just yet. But recently this is what's been happening.

-My boyfriend told me that my boobs are getting bigger.

-My appetite Is beyond weird. The smallest thing I eat makes my tummy queasy..

- And ive became very emotional. Literally everything gets me either so hapoy that I cry, sad that I start to cry, I get crankier than usual over the smallest thing. It all happens in the smallest amount of time.. Its weird!
