Anyone ever tested felt like it was gonna be negative but surprisingly positive?

I know I have no choice but to test and I am super nervous. Deep down something is telling me it's negative. I wish I had pregnancy symptoms but I have nothing. I'm irregular I didn't have my period last month only a light brown discharge for only 3 days I think but usually the next month I would get my period. I just really want to wait until I miss my period again but my boyfriend keeps telling me will you please just test and if I do and I get a bfn I am going to get discouraged and stressed Tf out and I don't want that to happen. I'm terrified of seeing a negative again since its been 15 months. I know I have no choice I have to test but can I just wait till I miss another period? 😞 please don't be rude thank you.
