I'm rarely regular or on time when it comes to my period but I had sex almost a month ago, right after I got off my last period and it's around the time when I should be having my next one. I'm starting to freak out a little because I'm not really having any symptoms like I usually do before I start my period and I just stared having brown discharge for a couple days now. I've heard this can be normal due to "old blood" or a warning letting me know that I'll be getting my period soon. When I had sex he wore a condom and pulled out, so I have no idea what this brown discharge could mean. I'm kind of scared.
