Will it work???!

Last month was not my month unfortunately but this month I really want it to be! So im trying different things this month..last month did not use anything.

*I have opks.

*I have a lube. (I went to look for the conceive preseed but couldnt find it anywhere in the shops 😔).

This is what I got. Has anyone tried durex and does it work the same as conceive? (As it does say on it that it kills sperms??? :/ )
