It was my first time using birth control pills [orthotricyclin] and to top it off i did not take it properly. i was supposed to take it the sunday after my period. i just took it on a sunday. on the second week of taking the bcp i started to spot. it was really light. at first i thought it was my period because the color was dark. this light flow continued for a few days. then the flow became medium. so i've been spotting/bleeding/period for about 9 days now, the flow varying from light/medium. should this be a cause of concern? i am not feeling any sharp abdominal pain. just a few days ago the color is dark red.

is this normal for first time user of birth control pill.
