Menstrual Cycle Day 18
What is happening internally?
The corpus luteum continues to release high amounts of progesterone, to maintain the uterine lining. The ovum (egg), if fertilized, changes from the ball of cells known as a morula, into a blastocyst - a cluster of cells with a fluid-filled cavity. The blastocyst floats toward the opening of the uterus.
Basal body temperatures remain high, above the coverline. Cervix is low, firm and closed. Cervical fluid is dry. You may be experiencing a little bloating or water retention.
