Hi, wondering if i am pregnant. I quit smoking 11 days ago (yay!) my last period started mar 30. I had sex apr 9,10,11 unprotected. Past few days i have been light headed at times, irritable and have this twinging feeling in my lower left abdomen. Today my left hip crease began to hurt. it's a dull ache that wont go away. Also i noticed a heightened sense of smell today. please help.
