Hi, I've been getting abdominal cramps , it only last for like a few minutes ,also sometimes I feel pain on my breast , and one day I felt like throwing up in the morning but I didn't , also when I wake up I feel dizzy for just a few seconds. My period isn't due until the 22nd of October? Also I feel a little bloated.

I only get cramps the first day of my period.

Am I pregnant ? Are these early signs of pregnancy?
