I have been on the pill for 5 months now. The first two months I did not receive a period, but for the past 3 I have received it each month on the same day and for the same duration. A week before my period was due this month I began to bleed light brown. On the first day, it was very light spotting, on the second it was heavier spotting (but only enough to wear a pantyliner), on the third it was light again, and on the 4th and 5th it has remained light. I had mild cramping the first two days and my breasts have been very sensitive. My period is now due in 2 or 3 days and I am planning to take a pregnancy test if I dont get it. Does this sound like possible implantation bleeding or am I making a big deal out of nothing? %-)
