Early symptoms

I am about 7 dpo. It has been almost 8 years since I've been pregnant. How early can pregnancy symptoms appear? My breasts are EXTREMELY sore. They have never hurt as badly as they do right now. Just my clothes touching them makes me flinch. I know between ovulation and period we can have a rollercoaster of hormones, but this is not pain I recall every experiencing. Anybody else have symptoms this early with a pregnancy that you recall? I won't be testing until after my missed period so as to not drive myself nuts overanalyzing the tests...which I have a nasty habit of doing!🤦‍♀️
