My cycle is a bit irregular this month and I have been using OPK's and temping, and i have yet to get a positive but my temps don't really show i have ovulated yet. Now i ran out of tests and couldn't pick some up until today so my worry is what happens if your temps show you ovulated and you don't get a +. It's just a fear and since i couldn't test the last two days i could have gotten a positive if i had tested. So after all that babbling just wondering if anybody never got a positive and what would cause that?
