Now I'm doubting my positive OPK last week. Wednesday evening it was negative, Thursday evening it was positive (I used the digi so got a smiley face) and then by Fri morning it was back to negative.
However, here's my concern. On Thursday when I got the positive, I was mega busy at work, and didn't have much time to drink much. So my urine was really concentrated...
Do you think this is the reason I got a positive?Bear in mind, I just had my D and C 17 days before my OPK and I've not had a period.
Also, what are the chances I actually ovulated (and not just a LH surge?)

Actually isn't there only a 12-24 hour window to catch the egg. So if Wednesday was neg and Thrusday pos and frid neg it would depend on times but you might have been in the 12 hour range. I am not overly familiar with the opks as I don't use them. I also thought they signaled the release... Heck I don't think I helped much. Maybe someone with more experience with them can help more. Sorry I just saw this today.
