I usually have light periods, but this month there is no bleeding whatsoever, like when I wipe I see a little color, but there is nothing significant, but I'm still having cramps. I took a pregnancy test just in case that came out negative. I'm on Yaz, so maybe it has something to do with it, I've been on it almost a year. I have also become a vegitarian within the last two months, but my period was normal last month so maybe that might have something to do with it. Has this ever happened to anyone?? I'm not too worried, but I just want to know what might be going on!
