Cramping but no period

Amanda

So I am 11dpo, I took a test this morning g and it’s negative. I’ve been cramping the last two days pretty bad making me think I’m definitely getting my period. I even put a tampon in this morning thinking there’s no way it’s not coming. I just changed it and there isn’t a drop of blood. I know I could still obviously get it, due on the 19th. Just wondering if anyone cramped really bad before getting a positive pregnancy test?
