Hello mamas so my period is 5 days late!

I thought my period was coming on August 10th but I really only got just brown discharge and I wiped once and I got maybe like a light pink/not quit red but no more through out the day just the brown discharge. I took a pregnancy test on the August 14th and it said negative I’m not sure if maybe that was too early to test but my period still isn’t here and I have been having cramps and throwing up but I also get like this before my period… when should I retest??
