Period or not?? Help please

Lizzy

From the 30th of November to the 4th of December I was spotting it first started light for the first 2 days where i really didnt need a tampon or pad but on the 3rd day it was heavy one time I peed and there was a chuck of blood when I wipped ive been having cramps since the 30th my boobs hurt my fiance and his friend said that my boobs look like their have gotten bigger my back hurts ive been moody/sensitive between the 27th and I think the 30th I was throwing up and had diarrhea I can't remember what days it was but I was sick for 3 days before I started bleeding than on the 4th I was sick again not as bad but still now today the 6 ive noticed that ive spotted twice but with brown the 1st time was light now the 2nd time there was a lot even when I wipped... My period was supposed to be yesterday the couple people ive talked to said I could be pregnant.. I'm nervous to test because I want a baby I really do but I feel if I test it will be negative... I'll be super upset if im not because my fiance and I have been trying..
