They are stashed in a cabinet ready to use. Dh could theoretically see them if he needs to get some TP since that's kept in there too. But usually I'm the one who changes out the roll.
I've got 3 cheapies from the lab I work at, 2 cheapies from ebay that are supposedly sensitive to 10 uL (those are the 2 types I have been testing with each time), 1 dollar store, 1 Answer early result, 2 Clear Blue +/-, 2 Clear Blue digitals, and 1 FRER. I've kinda been saving the best tests for when I get a BFP or think I may have a BFP.
Opks are kept in another cabinet so I don't confuse them with the pg tests, I have 2 Answer OPKS, 11 of the "good" cheapies, and 16 of the "not so good" cheapies, which is what I've been burning through this month.
