Bbt dip

Okay, so I’m 6dpo, today my bbt dipped by 0.57. For the past 5 days it’s been up. Anyway, i know implantation can happen 6-12 dpo. But, I’m just wondering if anyone DIDNT feel implantation. I haven’t read felt any sort of cramping today, maybe a tiny bit here and there but, I’ve also been pretty busy today so I may not have noticed too much. I haven’t spotted or anything either. My boobs have been more sore than normal though & my mood swings have been off the charts 😂
