PLS HELP

so I’m currently 20 days late for my period. I didn’t get my period in May which was due at the end of the month and my next period is due at the beginning of July. so I didn’t get it in May and as I said I’m 20 days late. I took a pregnancy test and it came up negative (see pictures) I just wanted to make sure it’s negative and get a second opinion. I’ve skipped my period before so I’m not too concerned. I just didn’t know if I should test again, wait until I get my period, or if I’m in the clear of not being pregnant...
