Dull aching/cramp like pain in lower back

Kaitlyn • Mommy of 2: Addyson Rose 03/27/18, baby # 2 due Dec 2019

Anyone experiencing a dull aching cramp like pain in their lower back? This is my second pregnancy and I don’t remember feeling this until I was in labor with my first. Just wondering if this is normal or something I should call and ask about. I’m 10 weeks and 4 days.

Update; I just read something about sciatic nerve or something and my left thigh has been numb so I’m thinking it may be that. Any ways to relieve it? ☹️
