Expired OPKs

Heather • I am 27 and have been with my DH for almost 6 years. We just got married 2 months ago but we are ready for his #2 and my #1. He has a DD that is 5 years old and we both love her so much! Baby dust !
What do yall think of them? Have they worked for you? My doc wants me to get the clearblue digital but they are so expensive. I found some on ebay but are expired.
