My cycles vary from 29-37 days. My last period was the 15th of March. 7 days ago I started getting brown tinged discharge. Then it turned into brown spotting. After two days it went a bit reddish then back to brown again. After 3/4 days it stopped then started again the next morning. It wasn t enough to fill a pad and is only noticeable when I wipe. It got a tiny bit heavier a few times. On and off. I then had a bit more red blood. It soon went back to brown. This has been going on for 7 days! I took pregnancy tests as soon as it started and every day since. All negative. I ve never had a period like this and I have been having them for 10 years. They are normally heavy with dark-light red blood and it lasts 5 days.
