Hi, I know I'm young at 15 but I'm worried...I had sex five months ago and then again four months ago that time with a condom. I had my period for the 3-4 months after but now month 5-6 im 15 days late. I have pain in my lower back and a weird clear/white liquid coming out of me. It completely soaks my underwear. I'm really scared I took a test a month and half back but it was negative.. I may just be paranoid and it may be stress why I'm late because I've been pretty upset at myself for losing my Virginity so young... Just please help me out.
