Last month I switched to a generic form of my old because pills. I missed at least 4 of my pills! Me and my boyfriend had unprotected sex all throughout this month. I spotted a couple of days but barley any. (tan,light pink,brown color).. I have recently been feeling really sick at night, heartburn, emotional over everything, pooping differently, and I woke up one morning, felt really sick & threw up. My boobs feel different, the areole is darker, looks like my areole & nipple are puffier than the rest of my boob. Am I pregnant or is it my birthcontrol? Help!
