Two days ago (13 days before period is due to start) I started to notice some brown blood when wiping. Didn't really think anything of it, so put on a pad. Now two days later it's getting heavier and yesterday for a time it was a darkish pink. I've had to put a tampon in as this morning when I got up quite a lot came out, but still not really like a period. I've also had a headache for two days. This has never happened before. I'm 46 and am experiencing certain symptoms of perimenopause - predominantly joint pain, sleep disturbance and mood swings, but my period has been ok up until now, although my cycle is a bit shorter by around two/three days. Has anyone else experienced this? Is it normal? It's definitely gone beyond what you would refer to as spotting.
