I am on medications from last 6 months. I am having regular period for first 3 months post my medication starts, but now from last 3 months I am not having my periods. I don'w know what went wrong. Me and my husband doesn't have sex due to some internal disputes. So no chance of pregnancy. Please let me know how can I start my periods again. My medicines are Sulpitac OD 50 and Qutane 25mg. Is there any relation of my period with these medicines.
