I’m not due to have my period for another 8 days and yesterday I had quite a lot of brown snotty discharge. I thought oh that’s early but accepted it was my period. So I had a shower put a trash pad on and now there’s nothing. Yesterday when I discovered it there was some reddish blood in the toilet and that’s about it. Usually I have tender breast for a good week before I come on and then when I do I get slight cramps. Yesterday I had lower back pain and today everything is gone. What is going on?
