2 weeks of waiting!!!

I'm so frustrated lately... I don't know how to live my life while I wait the 2 weeks to take a test. Do I drink that extra cup of coffee? Can I have the extra glass of wine? I don't know how to act. Act pregnant or not! I'm probably not but I could be? I read articles that say don't drink and don't eat high Mercury foods. But I'm not even pregnant yet!! My husband gave me such a hard time just because I wanted to go out with my girlfriends are m not binge drinking here. It's a glass or 2 of wine. By he goes on drinking as much as he wants but it's my fault if we don't get pregnant. I'm struggling guys!!!
