Pregnancy Symptoms

Okay guys.. So lately my last couple periods I've had no symptoms (like sore breasts, bloating, etc) just cramps (like normal) this month I've had bloating, very sensitive nipples, my back hurts, and I'm hungry, and don't have a lot of energy, very fatigued. Am I pregnant? (Which would be weird because I've been having protected sex, well half.. He goes in for a bit and then we do the condom and finish up.. precum? But we rarely have unprotected sex around O day.) So what??
