I'm new to this and need Help

My last period was June 6th thro the 9th. so I am now 13 days late no period. I've had a lot of symptoms that could be PMS or Pregnacy but the last test I took was negative after I got a faint line on one a few days before that. What should I do?? I don't wanna run to the doctor and it be negative cuz that will crush my hopes all together. I've been 20 days late before and had my period but it was horrible and painful with lots of clots and heavy bleeding. sorry if this doesn't make sense I just need any and all advice I can get right now.

first one I took this cycle all the others were either invalid or negative.
