A woman’s cervical mucus is stretched, but the result of testing with ovulation test paper is only one line, which usually indicates that she is close to ovulation, but has not yet ovulated.
When a woman is close to ovulation, the amount of cervical mucus produced increases and the cervical mucus begins to appear stretched. Most women will ovulate in about 24 hours when the cervical mucus is stretched to its longest length. Ovulation test strips are also a common method of monitoring ovulation. When a woman’s urine is tested with ovulation test strips on a regular basis, it will usually only result in a single line.
When the result of the ovulation test gradually changes from one line to two lines, it means that ovulation is imminent. When a woman’s cervical mucus can be stretched to a very long degree, and at the same time the ovulation test paper test shows a very obvious two lines, it generally indicates that in the last one or two days to ovulate.
