I know that some people have brownish discharge after their period, but is it normal to suddenly get it when you never have? I am a little worried about it but on the other hand as I'm getting older I am noticing a few weird things going on with my period (early or late) so I'm trying not to freak out.
I wouldn't worry about it. My period is, when it starts out, it is light bright red for a few hours, heavy deep red for about 2 or 3 days, then lighter and brownish for about 2 or 3 days. It is the end of your period, and it has been building up for a couple weeks before it starts to come out.
You can always call your GYN and talk to a nurse. Just ask her if it is something for you to worry about, she will let you know.
I actually had this start happening to me at one point when it never was that way in the past. Usually it was just red... and then one time I got the brown, older blood at the end and once even at the beginning. It's normal and can just happen with time. It doesn't even happen to me every time!
