| It is def a sign that you are ov. I think it is were the cervix softens and becomes sperm friendly . Its starts a couple of days before ov and usually dries up just after.
oestrogen levels rise, cervical mucus will be felt at the vulva.
At first it will give a sensation of moistness or stickiness and will appear in scant amounts - white or creamy-coloured.
On finger testing the mucus will hold its shape and break easily.
The mucus goes through a transitional phase where increasing amounts of cloudy mucus secretion may be observed.
It may be slightly stretchy on finger testing producing a wetter sensation at the vulva.
As the oestrogen levels continue to rise with approaching ovulation, the mucus will become more profuse, and there may be up to a tenfold increase in volume.
It will give a sensation of lubrication or slipperiness at the vulva.
The appearance will be similar to that of raw egg white, thin, watery and transparent.
On finger-testing this highly fertile mucus may stretch for several inches before it breaks.
Fertile mucus maintains the life of sperm, nourishes it and allows it to pass freely through the cervix.
In fertile mucus, sperm may live for up to three days, in rare circumstances for five days or even longer.
Peak day denotes the LAST day on which this highly fertile-type slippery, transparent, stretchy mucus is either seen or felt.
I know this is a lot of information but i hope it helps |
