OPKs while breastfeeding - Help, please!

I’d love other thoughts on this situation...

Here’s the quick story:

Still breastfeeding 11 month old baby. AF came about 5 weeks ago. About two weeks after that I got my sex drive back (which has been real low since giving birth). For that reason, and it being 2 weeks after AF, assumed I was ovulating, but can’t prove it. I have no idea how irregular my cycles still are. It occurred to me when AF didn’t arrive this past week that I may not have ovulated yet, so started taking OPKs. Got what looks like a peak this morning.

AF coming soon? Or ovulating soon?

Has anyone gone through this ambiguity when breastfeeding and cycles aren’t yet predictable?
