pregnant or just stress.??

Kayy
I haven't had AF since March, but multiple negative test. I've never had a regular period so I didn't think pregnancy was a possibility until I noticed I've gain weight, my boobs have grown, I don't eat or I eat very little then feel so nauseous I need to run to the bathroom. My fiancé's mother asked me while we were at lunch if I was and my first response was no until I took a bite of food and immediately ran to the bathroom. I have doctors Tuesday so fringers crossed that i am and it's not just stress😔😔😔
