That's a good question. Is this related to a procedure? Or is this just a wonky period? Abortion and miscarriage can create issues with our hormones as both can be a dramatic change (pregnant then NOT pregnant but hormones are still there). And bleeding after either is common.
Otherwise, if this is a goofy period --- keep track of it over time and show the information to your doctor. Let us know how it is going.
Did you have an abortion or a miscarriage?
