Confused

Taeler
So it's my first time being pregnant. I took a test yesterday and it said I was pregnant. Well underneath it said 2-3 weeks. Me and my boyfriend did it 3 weeks ago with a condom then a week later with out. I'm just wondering could it be from the week later time? But then could it be from the time we used the condom. I didn't trust the brand he used but he swore on it.
