Irregular period cycle or possible pregnancy?

Jana
My last period started May 3rd and ended May 9th, and I have yet to have another one since then.
​Going on 5 weeks without a period.
​I haven't had any "pregnancy symptoms" except for being tired a lot more often, I could lay in bed all day if I had the chance.
​I don't want to take a pregnancy test or get my self psyched out about it again when I know it will just be a BFN
​My cosy in dreamt me having a baby last week and last night she dreamt I had a BFP
​This could also be my irregularity coming back, before I was put on birth control I was irregular with my periods. 
​An advise helps!
