Numbness in my arm 36 weeks

Nikki • I'm 28, been with my husband over 12.5 years. We have an awesome 8yo son. I miscarried in 2015, due with our rainbow baby Sept 2020! 💕

I’m 36 weeks 2 days and I keep having numbness in my right arm off and on for the last couple of weeks. It feels like pins and needles. Sometimes when I lie down, both of my arms go numb. I’m also experiencing a shooting pain down the inside of my upper right thigh. I go back to my OB on Wednesday and plan to talk about it there, but I was wondering if any other expectant moms have experienced this?
