Pregnancy harassment

So I'm at work and the last 6 months my boss has continually asked me when I will start a family.  Although I am now actually pregnant she keeps asking me. It's made me very uncomfortable.  I told her that my personal life and my family growth is my personal life.  It's okay to ask about kids but the frequency in which she asks has made it very uncomfortable.  She apologized.  I'm only 7 weeks but again I don't know if I will have a miscarriage so these questions are super invading.  I am just hoping this doesn't affect my job.
