Hi, my temp went up this morning and I got a positive OPK at lunctime today (first one ever, woohoo!)

Did another OPK this afternoon (different brand) and the line was fainter, which leads me to think the surge has, well, surged.

Anyone care to take a look at my chart and tell me if you think I will O tonight or tomorrow? O was CD16 last cycle, but I have O'ed earlier in the past.
