It took me one try and it was an accident.
We were just having an amazing date night newly wed only two months. And he was to lazy to put a condom on. We weren't planning on trying to have kids for another four months. It was a total surprise four weeks later when I missed my period. The craziest thing of all is that it was a day after my period, I didn't think it was possible to get pregnant that close to your last period.
