should I be worried?
I am 24 years old, and usually have a regular period. My husband and I have not been preventing, but not trying really hard either to have another baby. I am now 8 days late (which has never happened before with the exception of my first two pregnancies) and having symptoms of sore breasts, nausea, tender lower back, tired a lot, etc, but have gotten 3 negative at home pregnancy tests. Should I be worried?
