Pregnancy test confusing

My period isn't due until Saturday, my boobs have been sore and gone so big for the last two weeks! Way different to when I am usually due my period! The excitement to test got the better of me so I did! It was negative which was disappointing but I know I tested too early, but this morning it was showing a faint line to be positive 😁 what could this mean? This is my first month of trying, can I do another test today or should I wait to see if I miss my period!! The waiting game is so hard 🫣
