A few days after menstruation
The level of estrogen and progesterone is low, so the mystery will presumably be little or not in any way. You may likewise see a dim deplete, however these are only the remaining parts of the blood.
Seven to 10 days before ovulation
Estrogen levels rise once more, and a solid mystery ends up plainly white or dim, somewhat sticky and thick.
The secret becomes more transparent and causative (according to the consistency similar to the protein). You will also notice that it is more healthier than in any other period of the month, as the level of estrogen secretion reaches the top.

Two weeks before menstruation
The level of estrogen quickly after ovulation starts to decrease and your mystery again winds up noticeably sticky and practically white or whitish and obscured. The nearer the new monthly cycle is, the level of hormones is lower.
