Period late by 5 days

So in June from the 6th to the 11th I got my period and then on the 16th to the 19th I got it again I had also got my first yeast infection around that time, And It got cured after 4 days. Then on the 3 of July it came back and it's fully cured as of today. I also took a pregnancy test, which came out negative on the 3rd of July too.

Now My period was suppose to come five days ago and it's still now here. What's should I do
