abnormal uterine bleeding
"I have been on Lo Loestrin FE for about 8 months.  I was placed on Lo Loestrin due to excessive bleeding as a side effect to another medication.  My cycles  over the last 8 months have been on one month and off the next month, however this month it all changed.  The week my cycle should have come on, it failed to do so and this would have been my on again month.  There is absolutely no chance that I am pregnant.  I started my new pill pack and my cycle decided to come on the same day.  I am now into my second week of blue pills and my cycle is still on.I can't take my other medication during this time because it causes excessive bleeding and clots. Don't know what to do next."
