Pre-menstrual Syndrome (PMS) Support Group
Premenstrual Stress Syndrome (PMS) is stress which is a physical symptom prior to the onset of menstruation. PMS is exceedingly common, occurring in 75% of women of reproductive age during their lifetime, characterized by symptoms of mood swings, depression, anxiety and irritability. It is often accompanied by physical symptoms such as bloating and cramping.

I am new to this group and I am just going through the posts. I know this post is old but I do have a question. What was the reason you asked your question. I am asking because I recently started gabapentin and my cycle has been way off! Just wondering if I should question my doctor about it or look farther into it.
Thanks,
Jessica
"Medications are a common cause of irregular periods. Anti-psychotics, anti-depressants, weight loss medications, steroids, hormones, and ADHD medications are some examples of medications that can alter menstrual cycles. If you’re taking one of these medications and being to experience irregular periods, talk with your doctor. She may be able to adjust your dose or switch you to a different medication." from https://www.verywellhealth.com/first-periods-3520908
