No period for 4 months

Bethany

So I have pcos and haven’t had period since 9th June and 2 days ago I wiped when I went for a pee and had blood mixed with cm and then after it was just pink when wiping. I haven’t had it the day after or today. I have also been taking opks but haven’t got a positive yet but not sure as not tracking properly. But Is this implantation?
