On bcp for 3 months, breakthrough bleeding occurred only in 1st month, no breakthrough bleeding since then. now spotting on 3rd month in the middle of a pill pack. need 1 more week until placebo week. did not switch. never missed. is this normal?

Spotting on BCP's ?: The most common reason for "spotting" on the current low dose oral bcp's is not taking the active pill within the hour of the previous day's active pill. The dose is so low, that even a few hours delay may cause withdrawal bleeding/spotting. If this continues, stop the pills, wait five days and start a new pack, keeping punctual in taking the active pills.
