Period or Pregnancy Symptoms

I am confused. I haven't gotten my period this month, but then again I am irregular.

When I'm going to get my period , my boobs get swollen. They're already swollen , but it's been 4 days! I usually smell something and I get cramps , but I haven't had any. I eat spicy chips , and I get no cramps.

I feel wet and go check myself and it's just gooey white stuff. I don't know what to think, it's very confusing.
