I'm so confused. I'm on CD23 and I thought 2DPO...BUT I did another OPK just now, just to check I, and I got this!! This is + isn't it? One minute i'm never getting any +'s then I get 2 in a week. Here's the one I did just now: and the one on Monday: I am aware that OPK's detect pregnancy but there is no way surely?!
