Am I pregnant???

Cristal
My boyfriend & I have been TTC for years now. I had 2 miscarriages in the past year so I don't want to get my hopes up but I am a day late. I always start on the 28th day of my  cycle & I have been feeling a lot of discomfort. I took a pregnancy test but it came back negative. Has this happened to anyone before? I really feel like I'm pregnant.
