3 days late & confused

leiani • Happily engaged. We have been trying for 19 months. 2 months before we started trying I went into premature labor & lost my baby girl at 18 weeks.
Okay so I'm 3 days late & I took a pregnancy test the day I was supposed to start & when I was 1 day late but they both came up negative. A week & a half before my missed period I had cramping/twitching on the left everyday that would come & go. 5 days before missed period I had cramping that lasted an hour & it felt like I started my period but there was no blood. My breasts feel sore but are not tender to the touch. I've been nauseous but have not puked. Has anyone else felt like this & was preg? & even though I am late for my period could it possibly be to early to test?
