Hi Heartbreaker_20,
You mentioned a shot but did not specify what it was. Since you also mentioned bleeding since you stopped the shot, I presume you are a female and went off of a birth control shot? I am not certain that fainting, low blood pressure and fast heart rate are normal symptoms after going off of any shot. With your continual bleeding, it is possible that you are anemic and your cardiac symptoms certainly describe some sort of issue, perhaps an arrhythmia of some sort. I strongly encourage you to go to the emergency room as soon as the symptoms start up (go now if they are continuous). While it may not end up being serious, this certainly does not sound normal and you should seek treatment. Only a physician can diagnose and prescribe treatment for the issue.
Best of luck,
Monica M. Skidmore, MS, RD
