Not very runnie and its not very thick I don't know what it is I just want to have an idea before I make a doctors appointment. See I'm on the patch (birth control) I've only been on it for a week the week I was on my period. Once my period stopped I dushed like 2 days after and had sex the same day I had dushed. The very next day this brown not to runny and not to thick stuff appeared in my underwear. My stomach hasn't hurt or my vergina while this stuff was appearing. Now it is week to after my period and I having sex and it still hasn't went away should I see a doctor?

It could be because of the douching. Douching is very bad for you. There's no reason to douche, your vagina is self cleaning, and douching can actually cause problems.

Brown blood is old blood, but it doesn't usually last as long as you've described. I would definitely see your doctor, tell him/her that you're douching and having sex, and on the patch as well (because that may also have something to do with this discharge).
