Golf -- Agreeing with the others, just too expensive... but I'm pretty lucky, I usually get a REALLY strong line the day before Oing. The day of O, it almost always is quite a bit lighter then the previous one.
Outside -- I get what you're saying now... I'd say try charting on fertilityfriend.com ... it will give you a clear picture of your cycle to see if it is normal.
As for the water trick, it's a way to tell whether it's EWCM or DH by taking it and putting it in some water. If it breaks up easily, it's more then likely DH's deposit. If it stays together, globs up and sinks, it's more then likely EWCM. It has helped me on several occasions when I couldn't tell for sure.
CLH: Hope you get the SA with no trouble and hope it goes well
AFM: I was almost positive I would be Oing today as I had some ovulation pains late last night and a small amount of EWCM yesterday. I usually get a LOT of EWCM along with much stronger O pains then I did last night right before Oing. However, today I have had NO O pains and VERY little EWCM so I'm not sure what to think... I wonder if the O pains happened while I was asleep and missed it and maybe I'm not getting the EWCM because we have been BDing so much? I remember when I was TTC my daughter, I never seemed to have much EWCM unless we took a break and then all the sudden I had a LOT. I don't even know if it makes sense but is it possible I'm just not getting the EWCM because we're BDing so much? And no, I'm not confusing it with DH's deposit because that's not coming back out either!!... I don't know where it's going unless it's mixing really well and going up inside to my eggies! Now I'm kicking myself for not charting this cycle... ugh!
