I got my cycle on January 25th but today which is February 12 I been sick all night and all today with throwing up everything I eat. All my friends say I'm pregnant but I think it's a stomach flu. Because the last time I got pregnant was back in "2008" with my son who is now 8. So I'm thinking I can't get pregnant, and yes me and my bf doesn't use protection and I'm not on birth control. So you guys tell me what you think ?
