I am 16 years old. I had unprotected sex with my boyfriend on the fourth of July, and again on the ninth. Both times, he did inside of me. I have taken three pregnancy tests. One came out positive and two came out negative. I am now experiencing white and clear vaginal discharge. Fatigue, cravings, bad mood swings, bloating, gas, and my period is late from what I know, by eight days. Am I pregnant?
