Hi I'm only 21 but I'm pregnant termination isn't an option for me anymore but I have parents from the south who are very strict in a way . in May I'll be graduating from College with a degree in sociology plus I'll be moving into my apartment next month . My boyfriend has a job as well as me . I just need suggestions on how to tell them because I'm very nervous although I accomplished something major in my life in May with them it still will be to soon for a baby .
