I can understand your anxiety. If you are feeling these symptoms then you should call 911 before you actually "pass out" from severe blood loss ("last night i was passing some blood clots but today i have been passing huge bood clots"). You might need a blood transfusion depending upon your CBC; therefore, it would be beneficial to telephone 911 since nobody is there with you to drive you to the ER.
Loss of blood can cause cold intolerance ("last night it was 80 degrees in my home and i was literally cold to the point of trembling"). Depo-provera can cause hot flashes but rarely have I heard of it causing cold intolerance. During perimenopause, sometimes birth control pills help with very heavy, frequent, or unpredictable menstrual periods.
During perimenopause women first notice changes in their menstrual period which may no longer be regular. How much you bleed could change, as in your case, you could have a heavier flow and periods may last longer. These are all normal results of changes in your reproductive system as you grow older. Once you haven't had a period for 12 consecutive months, you've reached menopause.
