Brown stringy spotting

Amanda

For the last couple of years I have been spotting for about ten days before my period is due. It’s dark drown and stringy. It typically happens when I wipe after using the bathroom. I’ve been to multiple doctors and an endocrinologist for evaluations and all of the tests have come back normal. They say that it is normal for some women to spot before their period. I was wondering if anyone else has this issue? If so has it stopped you from conceiving a baby? Thank you.
