I Went To A Doctor And Had An Ultrasound Where

I went to a doctor and had an ultrasound where they said l had PCOS polycystic ovarian syndrome.Told the doctor my periods had not come for two months and l wasn't pregnant as per the tests. Instead the doctor gave me norethisterone Bp 5mg Remedica-Cyprus. Isn't it going to delay my periods the more? And what should l do cause am only 27years old and l have never had a child.please l need a solution before l can start taking the tablets.
