My period is really late and it came and went is this normal?

The last time i got my period was in February and over the weekend my stomach was achy and i was really nausea and Sunday there was only a little bit of blood but more brown than anything and there was a lot of clumps. This morning it was really faded like it wasn't there and like i still feel achy and like im hungry but i don't really want to eat and like i still feel kinda nausea but i just want my period to come since it hasn't been here for awhile and im not on the pill. So i just wanna know if its here or has it gone or whats going on!!!
