Negative results but concerned

I’m going on 3 days late now and I’m pretty concerned. I typically get my period on the exact day this app tells me I will. Little background: I am not on birth control, but we do use condoms. We do mess around a little before putting the condom on but when things get serious, we wrap it. I know with pre-cum there’s always that possibility, but not a high one. We’ve done this the past four years, there’s never been an issue but this time seems “different”. I might be paranoid or overreacting but I had all the symptoms of getting my period then nothing. I took a pregnancy test and it was a distinct negative. Should I wait to retest? Or am I in the clear? I want a little munchkin one day, trust me. Im just confused as to why it would happen now but never before. Little advice please
