I am seventeen years old. I am on birth control pills. My cycle is very regular (because of the pill and naturally). My last normal period was on 8/14/09. This month my period was suppose to come on Friday, it is now Monday. I have only had pink spotting(starting friday) and brown spotting today (monday). It is a few drops of blood at a time hours in between. I took a urine test today and it came out negative. What is going on with me? Any advice or opinions?

Oh and this past month I've missed my pill countless times and doubled up the following days.

Based on the information you provided your most fertile times to conceive would have been the 23 through the 28 and if it took that and around the 2nd should be the time you would probably see implatational bleeding but to be on the safe side to really be sure if you get the negative results get an ultrasound down that could never fail. Because my mother didn't know she was pregnant until she was 7 months and she was a tiny woman but I hope this helps and everything works out for the best.

Thank you so much. I still haven't received a period. I am a small person :-) I weigh only 100 pounds and I'm only 5'4. I think I might take your advice.
