Why do I have non-menstrual spotting?

There are several reasons for the appearance of spotting before the period. The main reason is a drop in hormone levels. However, there are other reasons for this.

Decrease in hormones during the luteal phase

Bleeding that occurs during the luteal phase is most often related to a drop in hormones. But what is the luteal phase?

The luteal phase corresponds to the beginning of ovulation and ends with the arrival of menstruation (or the implantation of an embryo if there has been sexual intercourse with fertilization). It is during this period that the body prepares for the potential implantation of an embryo and it is at this time that the uterine lining thickens under the action of hormones.

When ovulation occurs, the follicle released by one of the two ovaries is transformed into the corpus luteum, which will secrete progesterone. During this period, estrogen will decrease and progesterone will increase.

Progesterone is the hormone responsible for supporting the uterine wall. But, a few days later, the progesterone supply is depleted. This is when the hormone drop occurs, which will lead to the beginning of menstruation and a new cycle.

In some women, even a slight drop in progesterone leads to light bleeding.

Bleeding during the luteal phase can also mean that your progesterone level is too low. If you suspect that your progesterone level is too low, talk to your doctor.
