I am 11 dpiui (ovulation triggered, so that should be the same as 11dpo). Today I am having some light pinkish brown spotting. Originally, my period was due 2 days from now, but my ovulation was induced later than normal so, it should be here on Wednesday. Was my LP too short and my period coming early or could this be implantation? I had some mild cramps at 9dpiui - today not really anything - it's just kind of tight.

Help!
