Pregnancy and period

Symone • I am 24, I work at a childcare center! I have been married to my husband for about 4 months and together for 6 years
I really felt pregnant but my period started!? I'm so tired and I've had gas and my boobs are off and on sore I also had diarrhea but being tired is the worst symptom. My period was late but now it's here so could I be?
