I got my first shot in June of this and my periods stopped completely. I didn’t start noticing brownish discharge till the first last two weeks of that shot. When I went to get my second shot I asked my provider about this and she told me it was normal. Now it’s been a week after the second shot and I’ve noticed that on some days the discharge is more of a dark brown color or I’ll actually be bleeding. Should this spontaneous bleeding Still be normal or should I be worried?
