please give me your opinions asap! i’m going crazy lol

this may be tmi! but i’m 1 day late on my period as it says on this app . i had sex on the 18th and the 19th . last month on the 28th i started my period , where tomorrow is the 28th it’s making me so nervous . so i’m actually like EXTREMELY wet like super wet down there . i’m just curious if this means i’m going to start my period or if its just because im very very early . i actually took a pregnancy test last night and this morning the FR , and it came up an extremely faint line .
