OPKs always positive?

Context: I had a baby 3.5 months ago and every ovulation test I’ve taken since then has been either positive or very close to positive. I can’t seem to word my question right for google lol the results I get when I search aren’t relevant.

I’m exclusively breastfeeding my 3mo (and still nurse my 22mo)

After I had my first baby my opks were always negative until about 7 months postpartum when my cycles returned. (We tried for baby 2 right away and got pregnant the second month) I was ovulating a week later than I used to.

We are not currently ttc. I bled for one day when my daughter turned 2 months old and assumed it was AF to be safe and have been using opks ever since.

Has anyone ever experienced something similar? At first I was nervous thinking I was pesto O but after awhile I’m just wondering what could make me have a positive every day. (I’m not pregnant or on BC)
