... never had any problems. Just two days ago I started bleeding, light at night, heavy during the day and some slight cramping,but I am coming to the end of my second week in the pack. Earlier in the week I missed 3 days and I misunderstood the paper toook all three in a day and skipped a day then took two. What is going on, do I throw the old pack old and start new or just go see my doctor?
