Brown Discharge = Pregnant ?

So i had sex a little less than a week ago, maybe like 4 days ago. I am on the birth control patch and he used a condom. I recently went to the bathroom yesterday and when i wiped, there was a brown looking discharge that came out of me. I googled it and it said it’s symptoms of early pregnancy but Idk bc we used a condom and im on the patch. But these days i guess you never know. Please tell me your opinions
