Hope

Hey everyone! I hope you guys can help me.. I have been using OPK all week and can not figure out what day was my peek day. The are in order from oldest to newest. I think maybe it was number 2 but number 4 looks really close as well. We have been trying for about 6 months with no luck and we are really hoping this is the month but these damn tests are so tricky haha. Thank you in advance for any help! Needing all that baby dust this week 🤞😬
