I bought the Target Up and Up brand of OPK strips last month to try to catch my surge. It said on the instructions that they expire after 30 days. Does anyone know if that does happen that you are not supposed to use them after 30 days?
I have a few left from last month and I wanted to check before I used them. Thanks!

Re: Do OPK'S expire??
Sorry, I've never used Target brand. I use Wondfo OPK's off Amazon and they are usually good for at least a year (expiration date printed on them) but they are individually sealed. If the Target ones aren't... I'd probably buy new ones.
