Soreness in arm?

Kristina 👼🏼👶🏽

I feel silly thinking this might just be because I sleep on my left. But for 2 days I’ve had random soreness in my upper left arm. I’m 14 weeks, 3 days.

I haven’t done any exercise or lifting and I don’t recall hitting my arm.

Hate to call the OB for this and be the lighting stock of the office for being worried about nothing. Just wondering if anyone else had experienced this. Or would this be a serious concern?
