Aches in pelvis and side

I'm 13 weeks. In the past 24 hours I've developed this ache on my left outer thigh and on the outer side of my left butt cheek. I also have an ache around the back i the leg into my pelvis. It's all located on the left side. My question is-anyone else experience this? I don't know if it's sciatic or not. I will wait until Monday to call the dr. It's also sorr to touch in certain areas. Not horrible just sensitive.
