Im late for my period by 17 days. Ive never been late before? Im 24 years old. I took a pregnancy test yesterday and it was negative. I am very bloated... could it be a "bump"? I have cramps on and off.. but everything else is pretty normal? I'll head to the dr's on my day off for the blood test... but I'm wondering if anybody else has gone through anything like this?

It could be anything from just late, to an infection or more. And it may be too early for a home test, but your doctor should tell.
