Hi! I am a 27 year old w/c. I recently had a change in my regular cycle. I usually feel sick a week prior to starting and then start bleeding with terrible cramping. The bleeding is heavy the first 3 days and then stops. I then have one day without any bleeding and then one more day of spotting. Then, my period is over for the month. The first strange thing happen in June. I knew I was going to start and that was not surprise. The bleeding was a little lighter and only lasted for 3 1/2 days. I chalked this up to being in another part of the country. I live at 300 feet and was spending the week at an elevation of about 8,000 feet. Then this month I was 6 days late and kept feeling like I was going to start. Finally I started and had severe cramping. The cramping last a few hours and then it was over. The strange thing is that I had a couple real large black clots come out. After that there has not been anything else. It's as if my period is over and nothing happened. I am in fear that I had a miscarriage or something along those lines. Please help. Thanks.
