Passing out

Was taking a shower and it must of been too hot (I've done this my whole pregnancy but now I'm 20 weeks) and I started feeling sick and soon enough I was seeing nothing but black dots and I got out quickly and my mother was home and heard me and the most embarrassing moment is being an adult and your mother having to wash the shampoo out your hair in a bath like a child. 
Should've waited till hubby came home but was feeling so gross. :(
