Am I paranoid? or what

Ashli
Ive been pretty regular my whole life, my last period was April 26-28. I had sex in the middle of may and June. Now I'm still waiting to get my period. I don't have any pregnancy symptoms or anything yet. It's just unusual for me to be this late. Maybe I'm just paranoid. It has me stressing out. 
How early on in a pregnancy do you start getting symptoms. I've looked it up and each site has different answers. So I thought I'd ask mothers. 
Now don't get me wrong, I want a baby, I'm baby crazy, I'm just not at the point in my life that I want to start a family. 
Now I'm just rambling. Any input would be helpful. Thank you
