Hi Everyone. I am going out of my mind over here these past 3 Days.... I'm late. Which has never happened in the 16years I've had an AF! I took one test on 4 days ago and it said BFN. But I still haven't gotten AF, and my symptoms are crazy!

I have very sore boobs/nips, nausea like no other, my abdomen is bloated, but I have NO CRAMPS, I am constipated, no appetite (which during AF I want to eat everything in sight lol) what do I do? Do I keep testing? Where do I but those cheapie tests? help! Lol.
