Am I testing too soon?

My partner and I have been trying for a few months. We decided to not focus on 'trying' and just see where it goes. This month I thought I was definitely pregnant. Sore breasts, nausea, feeling super tired. I'm six days before my expected period and I thought I would buy a First Response as we were going out for dinner tonight and considered having a glass of wine. The result was a negative and I feel like I can't do anything right. I'm not one to whine or complain, but I thought it would have been a lot easier to get pregnant as every woman in my family has never had a problem. My relatives called themselves the 'fertile Mertlyes'. I feel a little stupid for getting excited. Can anyone relate?
