I apologise that this will be long but I'm freaking out. I'm now 18 and got my first period when I was 12, it was always irregular (got it every 2-3 months) until I was 16 and was put on a low dose contraceptive pill (due to becoming sexually active). Instead of my periods coming regular I had my period for weeks and then would have a few days break and then back to weeks of bleeding, so I went off the pill and just was frantic about condom use, I went off the pill at 16/17 and since then my periods were fairly regular until the past couple of months they have been becoming later and later, and now my last period is a month late and now experiencing thick brown clumps and brown discharge, the last time I had sex was the 25th of June and I always double check condoms and everything. Does anyone have any answers or have experienced the same thing?
