I am 16, sexually active, and have been on birth control for about 4 months now. I was told that if you skip your placebo pills at the end of your pack you won't get a period so one month I did this and my period started anyway. I had already skipped the placebos and continued to take birth control so even though I had already started my period I continued to take them to keep me regular, my period went as normal (besides the fact that it was still going when I was still taking the pill) and after it was supposed to be done I started to get this thick brown discharge. I started my period August 16th and my period usually lasts for about 5 to 6 days so it should have been finished August 21st of the 22nd but once the bleeding stopped the thick brown discharge came and has not gone away and its been a over a week later, and I'm starting to get worried.
I've heard this discharge is normal but for it to be going on for this long and for the amount to be this substantial is unsettling

Yes it CAN be normal and things like this can go abit perculiar at times I mean I've had a period for 2 nearly 3 weeks then had the next only a week later. You could have an sti if you don't also use a barrier protection like a condom. I suggest going to the doctors if it's unsettling you and if you're embarrassed about it you can always request a female doctor. Every woman has had a strange period or something go wrong down there so they'd be more likely to understand.

GRRR Im the same but know it has nothing to do with an STI as I've been with my partner for years an this has happened to me lots also and I want to know WHY? It is really embarrassing :(
