Hey. I'm 38 weeks pregnant and this past week for some reason I'm obsessed with arm and hammer baking soda. I'll take a pinch of it in between my fingers and swish it it my mouth and either just eat it or spit it into the bathroom sink. I do it two or three times a day and I've been doing it for like five days now. I don't know if it's the texture or taste or what. Am I going insane?!?!
