Pregnant?

June- My period was late by 5 days

July- I completely missed my period

August- my period is expected on the 6th

I’m constantly nauseous, sore/ sensitive breasts, light cramps, mood swings, a lot of clear discharge, etc.

Could I be pregnant? I was dumb and didn’t use protection many times, and if doing the math, it was on a fertile day that I had sex.
