Are we expecting too soon?

So my husband and I got married in March of this year. We have since been trying to conceive... I am ALWAYS on time with my periods, but this time I was 3 days late. I checked numerous tests and all tested negative. Today, my period began and I can't help but feel upset that I had my hopes up. What I would like to know is are we getting discouraged too soon? I'm 27 yrs old and I feel like family and friends around my age who are trying to conceive have such difficulty doing so. I try to stay positive, but sometimes I can't help but think what if that happens to us? I guess I'm a little more concerned because I had a large ovarian cyst removed 2 years ago so I'm concerned it might be effecting conception.
