what is this TMI

ok so I'm currently 11 days late. I'm testing tomorrow with fmu. I have sore boobs, feel sick to my stomach I get tired very easy and have mood swings, fir example the fiancee comes home and tries to joke with me and it makes me upset and cry. I am upset for maybe a hour then I'm fine.my sex drive has been hit or miss. usually before my AF I'm horny 24 7, then while on it I'm have no sex drive and afterwards I'm horny again. I've also been more gassy. and when I burp itbtatse like vomit, well I noticed this yesterday. there is very very little in my panties. also when I put on a pad or pantyliner. it's only when I wipe after using bathroom. could it be implantation bleeding. I'm totally lost,
