Not expecting after all.

I was 5 days late and ready to take a test on day 7. I'm on the pill so I'm never late. My boyfriend and I want a baby but are trying to wait another 6 months so we can have money and a better apartment but it's so hard waiting. I was so excited when I was late and so was he. But this morning I started my period and now I'm really down and upset. I can tell when I told him about it he was kind of down as well. Any ideas how to move past the sadness?
