Sorry - I know this has been done to death but can't spot a relevant thread! I'm sure I've seen lots of discussion on the benefits of blue vs pink dye in pg tests, and there being some really good cheapy tests you can get in bulk. Last time I just got first response ones, but they were expensive.
My cycle is really long and irregular so always a bit hit and miss about when to test, so good to have a bundle of tests and ones that are really sensitive in case I end up testing on the early side. Any recommendations? Thanks!
