Opk readings

Hi ladies.. we’re TTC and we’re now on month 6 because we had an early loss last year. Do these OPK tests look normal? It’s my first time using them and they don’t seem to be going down quick like I hear a lot of people say so naturally I’m getting worried???!..... please help. I think next cycle I’m not going to use the app because I don’t think it’s accurate enough tbh
