It is rare for PMDD symptoms to last more than 2 weeks, although this can happen in cases where symptoms onset with ovulation and persist into the first few days of bleeding (i.e. the follicular phase) or in those who have conditions (such as PCOS) which may cause extended cycles.
PMDD symptoms can worsen over time, especially if not treated. It is not surprising that PMDD can contribute to chronic feelings of anxiety and depression, particularly if the PMDD symptoms are not being adequately treated/managed and are causing impairment and disruption in the person’s day-to-day functioning.
In PMDD, the symptoms will only be present during the luteal phase - so in between ovulation until around the time of the period. If you are experiencing symptoms outside of this ‘window’, it is extra important to track your cycle and symptoms carefully to ensure you work with an experienced provider to ensure you are getting the right diagnosis, care, and support.
If you feel that you are having PMDD as well as depression or anxiety symptoms that extend beyond the PMDD “window,” it’s best to talk with your healthcare provider to determine if you have another diagnosis in addition to PMDD.
