A response would help

My period is due on the 8th, and last me and my boyfriend had sex, he didn't pull out. We are trying for a baby. Well the past couple days ive had some cramps come and go, ive been beyond exhausted, n get out of breath very quick, been bloated, my gums bled a little today when i brushed my teeth which they never do, i had a craving for hot sauce on my chicken the other day, then lot of chocolate, i wanted a vanilla milkshake today n dip beef jerky into it,ive had a sore throat come and go a few times and ive been sneezing alot.Whats goin on? My period isnt due until the 8th, but could i possibly be pregnant? I really hope so
