How are things? I have spotting/bleeding with all of my pregnancies. This one it's ranged from pale brown cm when I wipe, to pink and red. It started just past six weeks, and has been on and off since. I'm pretty sure the cause of mine is a polyp as I'm pretty sure that's what I can feel on my cervix.
But it can be just because you're due your period and you can have spotting or light bleeds around that time, which can continue for a while, or it could be leftover from implantation just working its way out, it could be from sex, your cervix could be more sensitive or you could have something like a polyp causing it. Lots of reasons, the majority being harmless
