I was due to start my period a few days ago..the night after I thought it should start I had some really bad pains. I got a little worried because I had a miscarriage last year and was thinking that maybe thats was what was going on for a minute..the pain was on and off for the rest of the evening and into the next day. this morning I woke up and I was bleeding pretty heavy forvthe first day of my period. I was a lite achy throughout the day and took some painkillers to ease the crampiness.at this moment I am not having any discomfort but wondering what this glittery feeling in my back area right at my waist or near my kidney might be...
