Is my menstrual cycle normal?

Q: I am a 28 year old girl. I got married in April 2007. I am having problem with my periods. My cycle is of 22 to 23 days. Since the past one and a half years, it happens 7 days early than the normal time. Will this create any complications in pregnancy? I do feel pain on the first day of my period and the flow is also high.

A:There should be no problem, as this is within the normal range for period duration and cycle.
