I'm 19 years old and I've been with my boyfriend almost a year. We've never had sex but we've grind in the nude. Pre ejaculate has rubbed on the outside of my vagina and on my vagina lips. This has happened 2-3 times over the last couples of months but that's it. I've barely any periods the last 2-3 months with none of my usual PMS symptoms like breast tenderness, bloating, cramps until this month. Right now I have all of my usual, normal symptoms but a light period.. Am I pregnant? I've taken 2 tests but they both said no....
