PMS (premenstrual syndrome) symptoms leading up to the start of your period are quite common. There are medical and non-medical things you can do to help you feel better during PMS. See www.JeanHailes.org.au factsheets for more information. Make sure you get a good night’s sleep, eat healthy food and do some physical activity every day. A healthy lifestyle helps your body handle whatever challenge comes along. PMS often comes and goes during a woman's life. It's hard to say if the medication is related but if your symptoms are severe, see your doctor.
