During normal menses it is not unusual for some women to experience an increase in a sad or anxious mood. This is due to the fairly rapid change in female hormones during this part of the menstrual cycle.
Does the same thing happen to women using combined oral contraceptives (OCP) the week when the pills do not contain hormones and when menstrual bleeding happens (the “pill pause”)?
Researchers wanted to find out [see the reference at the end of this article]. They compared women on OCP with women of the same age who were not taking oral contraceptives. The women recorded their moods during their menstrual cycle.
The results showed that the women using OCP “had significant mood deterioration during the pill pause.” The mood changes were comparable to what the women who were not on OCP experienced during their menses.
The researchers also noted that the “mood worsening during the pill pause was more pronounced in women with higher baseline depression scores.”
Thus, taking a one week pill pause each month did not benefit women in terms of reducing their experience of negative moods during menses.
As the researchers put it, “Therefore, whether a pill pause is advantageous from a mental health perspective is questionable.”
So, what benefit does the pill pause provide? It does reduce the risk of breakthrough bleeding, and having menses reassures the woman that she is not pregnant.
However, there are many women who do not believe that these benefits are reason enough to deal with a monthly menses and the associated mood changes while on OCP.
It is generally considered safe for many women to take an active pill continuously (i.e., omit the pill pause). However, before any woman decides to do that, she should consult her physician. There are situations in which omitting the pill pause would be contraindicated.
