I have not had a normal period this month. Instead I had brown discharge for a full week. I know women usually get this before and after their periods but I have not had a period at all. I have had one day where there was a spot of blood and that was all and the rest was brown discharge. After the full week stopped it was two days later that I thought I was going to start but when I went to the restroom all it was was more brown discharge but not as much as before. I do have sex with my boyfriend and we do not use protection, all he does is pull out. I have read up on this and it says it could be implantation bleeding. Any ideas as to what is going on with me?
