Ovulation question

[samoorah1983]

I used opk and got a smiley face.. Used it later in the evening and got a smiley face as well, but when I tested the following morning it was negative.. Is that normal? Am I supposed to have a smiley face the following morning or just this one day? That was a week ago... Any experience with this?

Yes it can happen that way. One month I got positive in the morning and it was gone by evening.
