Anyone else experiencing this?

So for two nights now, whenever I try to sleep I feel like there are tiny little ants crawling all over my body. Like through my hair, on my toes, up and down my arms and body - everywhere. I’ve even had my husband check to make sure there really weren’t any ants! Literally nothing has changed in our house or routine in that time so I don’t know what could cause this feeling. Anyone else? Any ideas as to what this is? I see my doc tomorrow and I plan to ask her about it because it keeps me up for hours! 34 weeks tomorrow
