Hi, I usually have a 33 to 35 day cycle and last week on my 28th day I noticed whilst going to the toilet that I had a pink look on the tissue then for about 3 days on and off I had brown blood. I am currently on my 39th day and have been getting sore nipples for a week now and still no period. I do have polycystic ovaries and in the past have had late periods. I also have had brown blood before about 3 years ago. Help??!! What do you think?
