BFN? My first time taking a test

I am not looking to be pregnant right now but baby dust to all of you who are trying, I wish you the best!!!

So my boyfriend and I had sex around the 14th/15th so it’s been a little more than two weeks. I took this test after my period didn’t come at all last week like it was supposed to. So I took one this morning with first morning urine. I used the First Response Rapid Response Test. Should I test again next week or is this reliable?
