Hi, I'm 19 years old and I've been having some symptoms. My breasts are sore and my nipples are constanstly hard which happened two weeks before my 'period'. About a week before my 'period' I started feeling sick when I eat at night and in the morning sometimes during the day. A few times I've woke up with it. I've been having headaches for about a week now. My 'period' was extremely light pretty much spotting. I took an e.p.t test and it came up negative. During the test I was still spotting a little. I still have these symptoms and my lower back is hurting along with some minor cramping. I've always been a bit stuffy with some sneezing but I don't have a cold. My boyfriend and I agreed to wait until my next 'supposed' period to see. My questions are should I wait and is it possible that I'm pregnant?
