I am 17, sexually active with my boyfriend, but we always practice safe sex. I have a very irregular period and it never come when I calculate it to (which drives me insane). I have been getting some brownish discharges lately, and the discharges have started to increase and they're thicker, resembling a period. Usually, my period is normal red and has more blood than this discharge thing. I'm just very confused as to what it is. Is it my period that's being weird, or is it something like pregnancy? Condoms aren't always as safe as they make it sound, so I've heard, so I just want to know... Thanks!
