I am 18 years old and my period was like clockwork. But the last actual period I had was in October, and I skipped November, but in December like the 2nd week into the month I had what seemed like a period except it was brown..it had no sent, and it lasted about 6-7 days..I used a tampon and I took it out like 4 hours later (like your supposed to) and there was nothing on it. The second time I did it (used a tampon) there was a small clot on it but it was like the first and White. The whole time I was having brown discharge istead of eriod blood. Is that normal?? What should I do???
