scared to the max

so I need help like bad... I might be pregnant and my period is supposed to occur in 7 days but I've been showing signs of pregnancy... my boobs are getting bigger and they are tender & sore & I've been having the most dramatic mood swings... my bf & I are most definetly not ready for a baby but every time I think about taking "the pill" my heart hurts & I burst into tears.... and if my family found out they would hate me & I would be a dissapointment ... what do I do?!
