Last period 12/25-1/2. had sex on 1/2,1/4, 1/6 and1/8. on 1/12 i had a dark brown discharge. next period due in 7 days. could i be pregnant?

Maybe: Your timing is good if you are trying to conceive. The brown discharge is not indicative of pregnancy. It could be from infection or spotting. I wouldn't worry about the discharge if it goes away. You will need to wait a couple of weeks before you can perform a pregnancy test from your urine. Read the instructions for optimal timing.
