Am i really pregnant?

Ok, well I have posted several questions about this topic already...but i've had new symptoms come up! Well, as i've said before i've been on the birth control pill since March...I accidentally forgot to take my pill a few weekends ago, and had sexual intercourse with my boyfriend of 2 years. For the past 2 weeks, I can hardly eat(trust me, i'm a big woman...so when I eat, I eat(usually)!), i'm very moody, I get a sick feeling(upset stomach) in the mornings and evening times, i've also been having some discharge, could these be signs of pregncany? I am terrified, cause me and my boyfriend are not ready for a baby, he has a 7 year old son and I have a 20 month old son, I don't know what to do! Someone please help me! I feel like its to early to tell if i'm pregnant through a test...so I am coming to all my yahoo peoples, please help!
