Early pregnancy symptoms? 4 DPO

Hi ladies! So this is my first cycle that my husband and I have been TTC, the first day of my last period was November 23rd and my ovulation day was December 10th and LH peak was December 9th. We’ve made sure to do the baby dance on LHpeak/high LH/ovulation days.

Since it’s our first time TTC, I wanted to know what is anyone else’s experiences with very early pregnancy symptoms and/or implantation symptoms?

I want to know if there’s anyone I could possibly tell it I’m pregnant before testing around December 23rd. As of right now on 4 DPO, I’ve had cramps today and been extremely moody. I almost feel as if I should be starting my period soon, which I know is definitely not the case since my cycle is extremely regular every 26 days.

What do y’all think?? And when do you think I would be able to take an early test?
