Maybe pregnant

So my period is about two weeks late. I took a clear blue test today and it came out positive with a very faint plus sign. Even though on the paper is says " it does not matter if one of the lines that make up the( +) symbol is lighter or darker than the other ; the result is 'pregnant ' I know I should be happy but I'm not as excited. Btw I'm married and I live with my husband we are both fairly young 21 and 22. Any suggestions
