Spotting 6 days before AF is due

Kaycee
Spotting 6 days before AF is due then none the next day and again today at 4 days before AF is due. I'm not sure if my body is just toying with me now because I wanna be pregnant so bad, if that is implantation spotting, or if AF just wants to make a sneak preview a week before expected. I have been regular with a 28 day cycle since having my Mirena removed in October. I'm not going to waste the money on a pregnancy test until I'm actually late. Just not worth the heartbreak. Feeling discouraged and confused. Desperately trying not to stress about it all, but my body keeps freaking messing with me then breaking my heart.
