Bad mom for having a sex blog..?

I'm 19 years old and I have a tumblr "blog". I've seen MANY moms, including ones my age, have accounts like the one I have (sex account). I've been called a bad mother one person even told me that I should abort my baby just because I post racy pictures of myself. My baby is due next month and I will love, take care of, and always be there for him. I don't see how pictures I post determine my parenting. What are your opinions on this?
