First time mommy

I am 9 weeks with my first baby. Around the time I would get my period every month if I was not pregnant I have a little bleeding. It always starts off as light spotting for the first day and the second day it turns into light bleeding, barley enough for me to have to use a pad. It usually only last the two days and my doctor says with some Women they experience bleeding every month around about the same time they would have there periods. I was wondering if there was anyone else out there going through the same thing.
