I came on my period on the 9th of nov and finished on the 14th of nov then 7days later I had spotting that went from pink to brownish and lasted 3 days I have never had any problems with my cycle and my cycle is always 23days I went to a family planning clinic and she told me that it could only be implantation bleeding?

Hi everyone I'm new to this and am having a little problem with my periods? I came on the 07/01/2011 and off on the 11/01/2011 I had some form of spotting on the 30th (very strange) I was due on my next period on the 4th of this month but still hasn't come (3days late) this is all very unusual for me as my periods are like clock work I also feel very bloated slight niggle pain in back and stomach but nothing bad constipated and very moody hope some 1 can help
