SO confused! OPK positive no AF - help

Allison

It took us 10 cycles to get preg with baby #1 who is 13 months old. I’m still nursing which has kept AF away. We are now very ready for baby #2 but without a period that makes it difficult to even try. 😕

In hopes AF will come soon since nursing has slowed down, I’ve been trying to catch my ovulation before the first period arrives. The last two months I’ve been using OPKs. Two months ago I didn’t have any positives but last month I had a week, 4 days of high fertility and 2 peak (smiley). I assumed bc I finally got a positive ovulation test my period would arrive this month but NOTHING. And I’ve taken many pregnancy test all BFN.

How could I get a positive OPK but not have a period and not be pregnant? Comments/advice? I’m so confused on what’s happening!!
