Anyone experience bleeding just a few days after positive OPK?

Tahney • Mama to my miracle baby Reagan Leann 11.29.16 and angel baby Josie 9.19.17 until we meet again♥️

I had 3 positive opks on January 8, and we did the baby dance the 7th, 8th, 9th and 10th.

Then this last Saturday I had some brown/light pink spotting that turned into period-like symptoms (bleeding, cramps). Today it completely stopped so I had two days of this. Could this be implantation or is that way too early?! I also have PCOS so I’m starting to wonder if that gave me false positives?
