I'm 18 and kinda figured something was up when I started getting sore boobs , cramps but no period and I started gaining some weight aside from that I'm a huge ice cream person but don't really feel interested in it I felt nauseous just thinking about it. Today I took a test and it came out positive, I'm thinking about abortion but my boyfriend doesn't want that . I do because I'm planning on starting college in a week and a half I'm terrified of my mother and I'm scared to tell her I don't want to stress her out because she's also pregnant. please help . Should I tell my mom?
