Please help!!!

Ok so I think I am 7-8dpo. I took a frer test yesterday... BFN! I had given up but today at work I felt a little nauseous so I said I would crack another one open when I got home and got a vvvvvvf line...... (As in so faint I can't even take a pic)
I am just wondering if this has happened to anyone else and if so what was the outcome??
Feel free to be brutally honest and smack me back to being the realistic person I usually am...🙈
