Multiple OPK peaks?

Does anyone who use OPKs get multiple peaks or peaks that literally last like a week?

This is my first month using them and I’m kinda worried something might be wrong.

Background info: I have fairly regular periods (but kinda long cycles but I get my period every month). Been TTC for almost 8 months.

I did get low LH with the strips in the beginning (so it can’t be the whole batch being bad)
