Month Long Period

I missed my period for 2 months in July & August. My period is usually every 31 days. I took a hpt in July and BFN. I went to Dr and had a blood test in August and another one in September. They all came back negative. I had brown discharge on 9/25 so I thought i was starting AF. AF finally arrived on 10/08. My period usually lasts 5 days. My period has been going on since 10/08. For the 1st 3 days it was really heavy. Then it went light after3 weeks and all of a sudden my period is bright red. Its off & on throughout the day, sometimes only when I wipe. It doesn't feel like I am on my AF bcuz I had no cramps what so ever. I went to 2 gynos & they cant seem to know whats the problem. I don't know whats going on. Now since Monday I had very soor boobs, like I do b4 I  get AF. I'm not bleeding its dark brown blood. If anyone has experieced this pls respond asap!!!

I had my period for 18days once but I was on the pill and the reason was because of the hormones...so I had to change pills. I'm not sure what the reason would be for you but brown blood means old blood. If you were just experiencing that when you wiped then that's just spotting and not a full flow. Your cramps and sore boobs probably are from your pending AF so maybe everything will get back on track after this. If not...visit a doctor again.
