fat face?

Le
So my fiancé came in my 3 different times and I started my period like the next day it was 3 days late. My aunt asked me if I was pregnant because my face is getting fat. I'm no longer on my period and I still feel nauseous and I'm tired all the time. But when I think I'm pregnant im not and now that I don't think I'm pregnant I got all these symptoms. I was also told that it's normal to have a period the first month or two and idk like I honestly don't think I'm pregnant but I don't wanna be caught by surprise
