CONFUSED! Positive OPKs...Four Days Apart?

So four days ago, I had a blazing positive opk with all the symptoms...and yesterday and today I had two more almost positive opk’s (the one posted was from this morning) although both were negative at night. No PCOS here.

(I know this one pictured isn’t totally positive since it’s not quite as dark as the control line but it’s pretty dark)....and chance it could be detecting pregnancy?

What gives??? Any ideas? Still breastfeeding and no cycle yet.
