So my period has been normal ever since I started, years ago. These past few weeks I’ve been under lots of stress, as I just moved 8 hours away. I was on my period during the moving process and then stopped, and that period was normal for me about 6 days. I then start my period again a week later, and it lasts 6 days. The blood was dark brown, but just as heavy as a normal period. About a week goes by, and I am having blood spotting, dark brown color again. What is happening?
