7-8 dpo symptoms? *update*

Yesterday morning, I woke up and had such vertigo that lasted all day, just waaaay dizzy, and towards the night a pounding headache. This morning I woke up, still headache, slight dizziness and a very sore lower back. Tonight I'm feeling kind of out of it almost like lethargic? And I have a slight bit of Basra and the pan from cooking earlier smelled AWFUL  and gave me a bit of nausea. So Iv heard dizziness and backache are normal PMS symptoms but the strange lethargic feeling and I think my sense of smell has been more strong makes me thing pregnant...HELP IS ANYONE ELSE HAVING SYMPTOMS LIKE THIS? has anyone got a BFP later having had these symptoms? So after I posted I was getting undressed to take a shower and idk why but decided to squeeze my right nipple and some fluid dropped out, maybe a drop, kind of clear kind of golden... WHAT THE HECK?! Is this normal?!
