6 weeks pregnant and feeling pain

I'm 6 weeks pregnant with my second child and it's been 4 years since I was pregnant so I forgot what it felt like early on. I haven't been to my doctor yet either waiting for my appointment though. Today I started having pain in my lower left region. It happened when I twisted or leaned back in my chair. I was trying to make it hurt so I could see where it's coming from and I think it's a pulled Muscle in my lower abdomen/upper leg area. Doesn't feel like it's coming from inside. Trying not to be a worry wart though. Anyone else having little pains here and here? I think I'm showing already too so maybe it's round ligament pains??
