You have been spotting for 15 days off and on you had a miscarriage at 3 weeks back in nov05 im really scared you called your doctor and they told you it was normal but im still scared plese answer?

Do you know you are pregnant now, have you had a positive test? Aslong as it is just spotting you are probably ok. This is what doctors are for, to tell you what is happening. You cannot miscarry at 3 weeks as you would not even know you are pregnant. If you miscarried 3 weeks after conception that is 5 weeks pregnant not 3 weeks.
