Hi I Have Been Taking Sprintec For 7 Months And

Hi I have been taking sprintec for 7 months and stopped them 3 weeks ago due to me constantly forgetting to stay on top of them but now I have been in the worst state of mind! I feel depressed, angry, experiencing back pain, and hot flashes. Is this all happening because of the pill? Prior to taking the pills I was experiencing heavy and painful periods along with bad mood swings and to be honest the pill helped a tiny bit with the mood swings and pain but not with the flow.
