Hey I'm sixteen and had sex with a boy Thursday night for the frist time(with him) its currently Tuesday andyesterday day morning when I whipped it had a little blood on it and brown stains and so I put in a tampon and when I went to take it out later it had brown goo with very little blood and has been like that for two days now its not that much goo but enough to get me worried. I had my first period at ike 11 but it was never regular I could skip months at a time so I got on the depo shot(birth control) and was on it for three tears and never had a period now I have been off the shot for a year and still isn't had a period so I went to the doctors and they they startd me ob birth control pills saying it might help regulate it and I'm on the last pill of my period week now. What could this be? If its from being pregnant how could it do that this early? Could it be an std? Or maybe because I isn't had a period in so long? Could it be from going from vagina to anal to vagina? sorry I need answers! Please

You can get pregnant when you have sex, protected or NOT protected. Mistakes happen, birth control fails.

Yes, you could be pregnant.

Yes, it could be a STD.

Yes, it could be an infection that traveled from your anus to your vagina.

Yes, it could be just about anything.

You need to see a Physician.

I trust you and your boyfriend are prepared to raise a child?

The brown goo may be just your regular discharge along with your menstrual flow as this can indicate old blood, that would explain the color being brown.
Your probably going to end your menstrual soon

Even if it is not your menstrual. Spotting may occur when your partner penetrates deep and irritate the uterine walls of your vagina
