Had sex first week of birth control with no condom brown discharge half a week later could i be pregnant? last period july 3-9

?error in dates?: It is march 2013 as i answer this, so you would be 7-8 months pregnant if your last perios was in july? If your stomach is large, you feel a baby kicking, and your breasts are enlarged and possibly sore, than you are pregnant. If your dates are wrong, and you had a brown discharge, you should see a gyn for a good clinical exam and discussion. Good luck.
