menstrual disorders
"I have been using Lysteda for the last six months.  It worked great the first 3 months.  But the fourth month I started having horrible lower back pain, the cramps came back but the flow was still light.  However, the last two months, my cycle came within 2 weeks and I have my cycle again.  According to the dosage and usage, I am unsure if taking it more than 5 days is recommended.  I had my cycle for 5 days, it stopped for 1 day and started back up.  Tried contacting my GYN but couldn't."
