A little advice

I am currently late on my period at about 5 days? I don't know if I'm thinking too much but I have very sour breasts? I've only been trying for 3 months as we stopped trying as before we were having no luck? I'm one of them people who are always too scared to take a pregnancy test as I don't want to be disappointed, I don't know if I believe it enough it'll come true I don't know! I'm also very regular on my period always before 30 days is up! Anyone felt like this? False hope?
