What do you think? Will I get my BFP?

I'd say maybe, but not based on your symptoms. Since we normally ovulate about 2 weeks before our period, and it takes several days after ovulation for the fertilization and implantation to occur, it seems unlikely to me that you'd be experiencing so many symptoms already. Maybe you'd just be starting to have symptoms if you conceived this month but from the way you are describing things it seems like the symptoms have already become a frequent occurrence. There's a chance you're pregnant but I would say it's probably 50/50 at this point.
