Anyone Has This? ☹️

Okay I’m only eight weeks and 5 days. Today I’ve been getting really bad lower back pain and cramping is very mildddd but uncomfortable like on and off, however I’m still feeling nauseous.

Is this something I should be worried? Why it feel like my period is coming arghhh, hope Baby is inside of me. 🥺🥺🥺

This is my second pregnancy with first baby.
