Bought the wrong tests - help!!

[KatyR]

So I'm on cd 24. Recently cycles have been 21 days but used to be 25. Bought what I thought were frer and tested with a bfn. Then I read the packet... I bought first response rapid detection. Are these just as sensitive????
The packages look the same!!!

Hey, I’ve made this mistake as wells I think the rapid response tests are 25mui/ml so not as sensitive. So expensive as well

I also made the same mistake. You have to use FR Rapid after missed af. So not that sensitive
