12 dpo!😢

Hi everyone

I am currently 12 dpo feeling some symptoms like flu,fatigue,mood swings,lost of appetite,pain in lower back at right side sometime ,pain in my feet /numbing feeling which I experience near my periods

What do you guys think should I wait to take preg test or wait few days

(I fear sex because of pain I don’t think I have done enough to get pregnant 😢)
