Symptoms before bfp?!

Anyone who's gotten a bfp, what were your symptoms leading up to it and what dpo were you? I'm currently 13 dpo and haven't tested yet, but have had many changes in cm (usually dries up right after O), and my breasts are sore all over, I'm talking even on the underside of them! It almost feels like muscle pain in a way. What about you ladies?! I'm curious!
