Soo, I need to know if im pregnant again or not?

Well Boone answered my last question. So please answer me. I have been feeling off lately. My boobs hurt just to touch them even walking down the steps at school hurts.. I pee at least 20 times a day. Maybe more. I get headaches Nd back pains... I feel so sick lately. and I have been super moody. Today I noticed I am getting sick to certain smells. so am I pregnant??
