Then 3 days later, I suddenly came on my period and I had to run to the bathroom, I thought my period
had started early
. So I carried on as normal, then the next day it had gone, there was nothing. But every day since then I've been having light brown discharge or a darker colour, today my period is due and I've got slight stomach pains as I usual do before I come on, it's darker than normal and I assumed I was coming on my period, but nothing is coming out.
