OPKs expire?

Kendra

I haven’t been good as using the OPKs and I think they might have expired. Could this happen? I missed a couple days this cycle and still haven’t seen a positive OPK...one day was REALLY close and the days I forgot were before & after that day 🙄. I’m trying to decide if I should get new ones and pregnancy tests. Thanks! I miscarried in 2011 and still struggle to actually try hard at conceiving. I’m now 36 and feeling time slip away.
