my period was about 2 weeks late, so i took a pregnancy test and it said i wasn't pregnant. so when i ended up getting my period it was dark-ish red, clotting, bad cramps, i felt sick like i was going to throw up, i couldn't even walk or stand cause my cramps hurt so much and that was first day i had it. the second day it wasn't so bad it was normal but lighter like i barley had it. then the next day it was gone. a month later i didn't get my period and my test came back that i was pregnant. so what happened with my period? i never had that happen before and my period are never a month a part or on time.
