abnormal uterine bleeding
"I am on my third and last package of LoSeasonique; it has been rough.  During the first pack, I started spotting daily in week 5.  This progressed to a full fledged cycle by week 9 and lasted for three weeks, so my doctor instructed me to skip to the yellow pills and then begin a new pack. During the second pack around week 5 the spotting started again.  During week 8, I passed out. In week 10, I began having extremely heavy bleeding that proved impossible to contain resulting in two terrible accidents.  Thank God I was home both times.  After getting the next prescription and reading the pamphlet again, I discovered all of these experiences are considered severe side effects of the pills. "
