Should I worry?

Okay so I know you shouldn’t google your symptoms lol😂 they always diagnose me with something terrible but I can’t help it. So I am 6 days late on my cycle. I’ve been having a really watery discharge and for the past 3 days it’s been pink but now there’s nothing. Still no cycle or discharge. I have some light cramps throughout the day. I have been feeling sick and stressed so maybe that’s why it’s late but umm it’s 3 days left in the month and I’ve never been irregular stressed or not. What do you guys think?

UPDATE!!!!!!!!

So I took one of these 89 cents test just now and it was negative. That was all the store had and I just got off work and didn’t feel like going to Walmart. Should I retest later? Still no cycle also.
