Pregnant or ??

Af was due 6/17. I still have no symptoms of it coming, just mild cramps a few days ago and sleeping a lot. I want to test but the fact that I've been late these past 2 months (last month I was a week late) I think I should wait a little longer to see if AF shows. I'm also worried about other health problems with me being late 3 months in a row,  before then I always had a regular cycle. Has anyone experienced anything similar?
