Augs 19 my period started augs 20 my man in me while I had a tampon on by augs 23 my period stopped today augs 25 I spotted brown discharge, could I be pregnant?

Did you remove the tampon after you had sex? I'm a bit shocked you left it in, there are so many thing that could go wrong by doing that, none of them good.

You had sex, so yes, you could be pregnant. Are you? We don't know, and you won't know for at least another 4-6 weeks. You'll have to wait until your next period is due. If you miss it, wait 2 weeks, then test using first morning urine.

If you want to lower the odds of pregnancy, use protection. It's best to double up, pill and a condom. But, even if you use protection, pregnancy is possible.

Never ever ever ever have sex while wearing a tampon. Very bad idea.
