Hi, I'm 20 years old and I've been on birth control for about 8 months now. I missed a pill the other day, and I made up for it the next day. The day after all this I was bleeding a little (I'm not supose to have a period for at least another 2 weeks) and I got a little worried because my last period before that was really light. I heard a light period and spotting between could mean pregnancy. Since then I missed another pill and have made up for it once again, and now I'm feeling really cramped. Is have cramping and spotting normal for missing a pill? and exctly how light can a period be before you need to be worried? Thanks!!!
