IMPLANTATION BLEEDING???

Sierra
HELP! I have never had ANY spotting before I get my period, it's literally just BOOM and AF shows up. But my period says it's due 3/24 (one week from today), I'm currently experiencing very very light pink tinge when I wipe (will post pic) and my boobs have been a little more sore then they usually are when AF is coming. (Normally it's just one boob.... It's both right now) and I'm NERVOUS AS Ever to get my hopes up. I have been taking folic acid in 800mg capsules daily. Could This be it?!?! **Fingers Crossed**
