Implantation ???? HELP!!

Okay ladies long story but last cycle was cycle 4 after being off bc and it went haywire and ended up being 43 days long first three cycles post getting off bc were 28 days. This month I ovulated the 9 th. Then on cd 36 I started spotting very light pinkish discharge bug big a lot absolutely no cramps just bloated and tired. Now today day 4 of spotting Iv been getting small spurts of blood but still no cramping and it's not steady bleeding just enough to notice more when wiping and on a panty liner . From what I read this could be implantation what do u guys think  . I'm confused
