Dear doctor: Having 28-day menstrual cycle. Last period started on October 2, 2016 and lasted until October 5, 2016. Now, seen a little bleeding today morning (October 13, 2016, one week after the menstrual period). We are newly married (marriage date sep 4), trying to get pregnant and having daily intercourse. What might be the cause for bleeding and what is the possible time to get pregnant? Thank you.
