Pregnancy Symptoms?

Bridgette

I have unprotected sex two after my period in June and again three days before July. I recently got off my period 5 days ago. The last week, I’ve been feeling extremely dizzy, nauseous (no throwing up), fatigued, and sensitive to smells. I’ve also recently felt extremely hot at night and they feel like hot flashes. Could I be pregnant or does this happen to others after their period?
