Just wondering


So I'm 19 days late for my time of the month and I want to buy a pregnancy test but all the ones I find are for "5 days BEFORE missed period." I have had 2 previous pregnancy in my life and I've always used the test that you get from the dollar store but where I live now the only closest stores are HEB and dollar general, so my question is if I were to buy one of the test (the ones that gives the results BEFORE your missed period) can I still get a positive?

Thanks in advance for the advice😌
