Usually when my period ends I have this brown thing idk if I should call it discharge or if it's still blood. Idk. But recently I've been getting it and I'm not even on my period. Glow says my next period is April 20th and today's the 11th? And my stomach has been hurting on and off all week. I don't even know why. No I'm not pregnant because I've never had sex? Is there something wrong?
