Help! Any ladies with insight ?! ❓🤔❓

So husband and I are ttc. I’m currently in my tww, roughly 5-6 dpo. I’ve been cramping and my nips are super sore and sensitive. I’m having lower back pains too. My period is due Feb 6th. I know it’s early but has anyone experienced this and got a bfp later on? I honestly feel like I could start my period but it’s too soon. And mine comes like clockwork.
