I think for a lot of us ttc, the consensus is that AF's arrival is less upsetting than a BFN. I was totally there, but since my m/c I feel the opposite. Since bleeding was my first sign something was wrong, seeing blood on the tp when I'm still hoping to be pregnant just brings back bad memories. That being said, I don't really like negatives either. So when do you think, assuming a normal cycle, is the best day to test to have a lower chance of a false negative, but still before AF is likely to show so I have some warning that it's definitely coming? Maybe 12dpo? I'm starting charting this month, so I'm thinking the temp drop will give me the warning I need, but I'd like to test too.

Also, one article I read suggested that opk's (which I'm starting this month as well), can act as hpt's, and are even more sensitive. (Something about the proteins being similar enough that opk's can't tell the difference, so they detect pregnancy too, but it doesn't work the other way around with hpt's because they're more specific.) Does anyone have any thoughts on using them in that capacity?
