abnormal uterine bleeding
"Please avoid Tri Lo Sprintec. I've been on it for one month, and it has cased me to bleed every single day. I also had my period fifteen days after my last cycle (not normal). It's also caused dizziness, nausea at all hours of the day (to the point where it wakes me up in the middle of the night), and fatigue. Please research any birth control before you agree to taking it. Listen to your body when you notice changes after beginning this prescription."
