My period has been getting heavier since I started on Effexor 4 months ago. This time it s day 4 of heavy bleeding and horrible cramps. I use a 30 ml menstrual cup, and it has to be emptied at early morning, mid-afternoon, and evening. Each time it has been almost full to the brim of thin, bright red blood with lots of clots. Sometimes my diva cup even unseals within 6 hours from overflow! This is not normal for me, and I ve been very sick the last several months. This kind of period could put me back in the hospital. Is any of this normal?
