Hey I've started Angus cactus a few months ago TTC with endo and ? Pcos this month not BD too much and now I have stringy dark cm been having sharp crampy pains for a few days then last night and this morning brown d/c with a bit of blood. This is not normal for me my cycle is around 37 days so on CD 25 I'm worried!!. It's there only when I whipe or fingers in sorry TMI... Did a preg test BFN of course. Really worried as I have never had this!
