Period or implantation?

Dusty
I have a 4 day period with variation of cycle days between 28 to 30. I am NEVER more than a day early if that. This cycle i was 6 days early on my period. I only bled from sunday 11 am to 10pm monday.(2 days max) Today ( tuesday) was only one tiny dot. It was very light i kept thinking i would bleed more but never did. I wasted a lot of pads... i was supposed to start in 4 more days so i am gping to test for pregnancy then we have been actively trying for 9 months. Hoping this is it... what do u think? What do u need to know? The waiting is killing me. Ive been super tired and no cramps! Weird right???
