I had sex for the first time on January 15th, no ejaculation in me, but I was scared of pre-cum. We did use a condom but we kept taking it on and off (i know that was dumb). I took a plan b pill right after and I felt fine. About 5 days later when I woke up I was bleeding, but it was brief and the color was a bright red, and it subsided. My last period was on January 1st, and I am so scared right now. I am bleeding again on January 27th and i have cramps, the blood is bright red again. I know my period is due sometime this week but I am really scared. I not ready for pregnancy. Someone please help.
