There is nothing like one week pregnant. In normal case the pregnancy is confirmed only when you miss the period . in such case it is tested and confirmed after 10-15 days of period missing. by that time you are 6 week pregnant.
About your back pain do consult a good gynecologist. do not go for self medication.
