Am I crazy or possibly pregnant???

I'm 5dpo and I've had the weirdest symptoms! the one that bothers me the most is how achy and sore my boobs are. particularly around my armpits. plus I woke up from a nap and I swear they got bigger. anyhow anyone else have weird symptoms during your tww? what were they and did you get your BFP? I just wanna be sure I'm not losing my mind.
