***Trigger warning*** af?

***Trigger warning**

Pic will be in the comment, not any type of test but my back and abdomen has been cramping since yesterday and all I've been wanting to do after I get off work is sleep. Also been getting nauseating spells on and off. I'm 2 days late, if this is my period then it's just barely spotting since this morning. Not sure if its af or possibly implantation as I've never had implantation happen before.
