CRAZY CRAVING/ OBSESSION: EATING SOAP

I’m 40 weeks pregnant and 4 days. yipeee! Still pregnant. But lately I’ve had this weird problem where I always feel dirty. Like I always have to bathe and I don’t necessarily think I’m dirty because I don’t do much but I just feel that way. I feel icky otherwise. I have an obsession with dove bar soap since about last week when I started feeling like this and now I been craving it, like I wanna eat it. Like idk I don’t feel right saying that but it’s the truth, is it cause I’m pregnant or what? I don’t get it. I haven’t done it but I just feel so crazy
