Vibration in body

About 6 months ago I got high with my bf for the first time . I got this wierd vibration in my body that if I moved my hand around my body all I felt was little vibrations non stop , if I wanna touch let's say my arm hairs I cant feel them because of the vibration I feel on my body. I found out the weed was laced . But Im 18 weeks pregnant and out of no where I start feeling the same thing again , I no longer smoke . So I was wondering what could be causing this and has anyone else felt it ?
