menstrual disorders
"Loestrin is VERY effective as a contraceptive. However, I am on the pill because of irregular and painful periods. The pill is good but what bothers me is that my monthly cycle, though tolerable, is COMPLETELY UNPREDICTABLE. The first few months i had a period, short and light. Then my period disappeared, and I thought i was pregnant. My doctor told me this is normal with this pill. After two or three months of no period it came back preceded by cramping and severe nausea -- I thought I was pregnant AGAIN! The number of days between periods is not consistent. This cycle I was exhausted, nauseous and moody a week and a half before the  bleeding began. Now I am having nausea though physical symptoms usually disappear a day or two of bleeding."
